radio lcd screen repair free sample
I investigated my landline phone to repare its LCD according to this good tutorial, unfortunatly I found the cutted connection is not on the main PCB board but on the flat connector itself... and any heat applied (soldering tentative...) to the flat is going do destroid it completly ((
I had a Natwest Card reader, where the screen was illegible and using this tip with my wife"s hairdryer I got the card reader operational, many thanks !!!0
Many thanks for sharing the information on how to fix these displays! Worked out perfectly on a asus lcd poster from ages back which gave no screen at all and are not sold anymore to replace.ReplyUpvote
Very good interesting piece. I am no way shape or form of an electronics junkie , but i am more like a jack of all trades and a master of none type. I have a dual power TS-100 hand held calculator where the second digit was pixelated I would say. I googled how to repair it and seen your story. I took my calculator apart and the back side is where that glue strip is at. I could not find my heat gun, thanks to having to move it for the Christmas tree setup. I used my Kitchen Propane stove front burner and waived it over it a few times. It took a few tries but I finally was able to get the dead pixel back. One good thing is the calculator was on so in between heat ups and eraser rubbings I could see my progress and man your fix really worked. Thanks fro the story. My favorite pocket calculator is fixed once again. I wish I would have taken before and after photos, but was too giddy to try your repair idea.0
Google offers no link as to how to open an AEG Voxtel D235 handset. After opening the battery compartment and removing batteries and the two Philips screws at the bottom, the upper half refuses to budge. Is there a method for opening the upper part, to access the LCD screen connector for repair? Any suggestions appreciated.0
I just got my CM921 to work - so, carefully unplug or remove the lcd unit from the circuit board (8 pins i think) then separate the white board (same size as the lcd) from the back of the lcd display (it was glued on one side and i used a scalpel) the lcd will then flip over and you can see the ribbon, then follow the instructions above, return the lcd back down on top of the little white board as before and plug it back in...0
There may be a thin conductive rubber strip between the glass of the display & the board it is attached to. Over time this rubber can leak an insulating compound onto the interface connection that can, at times, be removed by removing the strip and gently rubbing it with a clean soft eraser. Be gentle as it can be fragile & easily damaged. This was an effective repair in the early days of these displays.0

The original Game Boy is a classic. Sure, it had no backlight, but there is something special about playing on that classic green screen. Unfortunately, some of these older systems are suffering a terrible fate — screen burn. Game Boy’s played best with lots of light — especially out in the sun. But that same sun did terrible things to the screen. A black splotch in the center of the LCD is the telltale sign of a burned Game Boy. You might think that screen replacement is the only option, but[The Retro Future] shows us how to repair this issue.
A reflective LCD is a layer cake made up of polarizers, two panes of glass, and a reflector. The burns often seen on Game Boy screens usually are in the polarizer and the optically clear glue which attaches the plastic polarizer to the glass. We’re guessing these burns happen when someone leaves their Game Boy out in the sun. Between the sun rays directly striking the top polarizer and the rays bounced back from the reflector at the rear of the screen, that poor polarizer doesn’t stand a chance.
Repairing the burn is a delicate operation, as one false move could crack the thin LCD glass. The first step is to carefully peel off the burned polarizer. This leaves a mess of dried glue, which can be scraped off or dissolved with alcohol. A new linear polarizer can then be placed on the front of the screen. [The Retro Future] chose not to glue the polarizer, but we’re betting some UV cure LOCA (Liquid Optically Clear Adhesive) from a cell phone screen protector would do the trick.
CUPERTINO, CALIFORNIAApple today announced Self Service Repair, which will allow customers who are comfortable with completing their own repairs access to Apple genuine parts and tools. Available first for the iPhone 12 and iPhone 13 lineups, and soon to be followed by Mac computers featuring M1 chips, Self Service Repair will be available early next year in the US and expand to additional countries throughout 2022. Customers join more than 5,000 Apple Authorized Service Providers (AASPs) and 2,800 Independent Repair Providers who have access to these parts, tools, and manuals.
The initial phase of the program will focus on the most commonly serviced modules, such as the iPhone display, battery, and camera. The ability for additional repairs will be available later next year.
“Creating greater access to Apple genuine parts gives our customers even more choice if a repair is needed,” said Jeff Williams, Apple’s chief operating officer. “In the past three years, Apple has nearly doubled the number of service locations with access to Apple genuine parts, tools, and training, and now we’re providing an option for those who wish to complete their own repairs.”
Apple builds durable products designed to endure the rigors of everyday use. When an Apple product requires repair, it can be serviced by trained technicians using Apple genuine parts at thousands of locations, including Apple (in-store or by mail), AASPs, Independent Repair Providers, and now product owners who are capable of performing repairs themselves.
To ensure a customer can safely perform a repair, it’s important they first review the Repair Manual.

Electromagnetic radiation consists of waves of electric and magnetic energy moving together (i.e., radiating) through space at the speed of light. Taken together, all forms of electromagnetic energy are referred to as the electromagnetic "spectrum." Radio waves and microwaves emitted by transmitting antennas are one form of electromagnetic energy. They are collectively referred to as "radiofrequency" or "RF" energy or radiation. Note that the term “radiation” does not mean “radioactive.” Often, the terms "electromagnetic field" or "radiofrequency field" are used to indicate the presence of electromagnetic or RF energy.
Different forms of electromagnetic energy are categorized by their wavelengths and frequencies. The RF part of the electromagnetic spectrum is generally defined as that part of the spectrum where electromagnetic waves have frequencies in the range of about 3 kilohertz (3 kHz) to 300 gigahertz (300 GHz). Microwaves are a specific category of radio waves that can be loosely defined as radiofrequency energy at frequencies ranging from about 1 GHz to 30 GHz. (Back to Index)
The energy levels associated with RF and microwave radiation, on the other hand, are not great enough to cause the ionization of atoms and molecules, and RF energy is, therefore, is a type of non-ionizing radiation. Other types of non-ionizing radiation include visible and infrared light. Often the term "radiation" is used, colloquially, to imply that ionizing radiation (radioactivity), such as that associated with nuclear power plants, is present. Ionizing radiation should not be confused with the lower-energy, non-ionizing radiation with respect to possible biological effects, since the mechanisms of action are quite different. (Back to Index)
The most important use for RF energy is in providing telecommunications services. Radio and television broadcasting, cellular telephones, personal communications services (PCS), pagers, cordless telephones, business radio, radio communications for police and fire departments, amateur radio, microwave point-to-point links and satellite communications are just a few of the many telecommunications applications of RF energy. Microwave ovens are an example of a non-telecommunication use of RF energy. Radiofrequency radiation, especially at microwave frequencies, can transfer energy to water molecules. High levels of microwave energy will generate heat in water-rich materials such as most foods. This efficient absorption of microwave energy via water molecules results in rapid heating throughout an object, thus allowing food to be cooked more quickly in a microwave oven than in a conventional oven. Other important non-telecommunication uses of RF energy include radar and industrial heating and sealing. Radar is a valuable tool used in many applications range from traffic speed enforcement to air traffic control and military surveillance. Industrial heaters and sealers generate intense levels of RF radiation that rapidly heats the material being processed in the same way that a microwave oven cooks food. These devices have many uses in industry, including molding plastic materials, gluing wood products, sealing items such as shoes and pocketbooks, and processing food products. There are also a number of medical applications of RF energy, such as diathermy and magnetic resonance imaging (MRI). (Back to Index)
For many years, research into the possible biological effects of RF energy has been carried out in laboratories around the world, and such research is continuing. Past research has resulted in a large number of peer-reviewed scientific publications on this topic. For many years the U.S. Government has sponsored research into the biological effects of RF energy. The majority of this work was initiated by the Department of Defense, due in part, to the extensive military interest in using RF equipment such as radar and other relatively high-powered radio transmitters for routine military operations. In addition, some U.S. civilian federal agencies responsible for health and safety, such as the Environmental Protection Agency (EPA) and the U.S. Food and Drug Administration (FDA), have sponsored and conducted research in this area. At the present time, other U.S. civilian federal health and safety agencies and institutions, such as the National Toxicology Program and the National Institutes of Health, have also initiated RF bioeffects research.
Exposure standards for radiofrequency energy have been developed by various organizations and governments. Most modern standards recommend safe levels of exposure separately for the general public and for workers. In the United States, the FCC has adopted and used recognized safety guidelines for evaluating RF environmental exposure since 1985. Federal health and safety agencies, such as the EPA, FDA, the National Institute for Occupational Safety and Health (NIOSH) and the Occupational Safety and Health Administration (OSHA) have also been involved in monitoring and investigating issues related to RF exposure.
Facilities under the jurisdiction of the FCC having a high potential for creating significant RF exposure to humans, such as radio and television broadcast stations, satellite-earth stations, experimental radio stations and certain cellular, PCS and paging facilities are required to undergo routine evaluation for compliance with RF exposure guidelines whenever an application is submitted to the FCC for construction or modification of a transmitting facility or renewal of a license. Failure to show compliance with the FCC"s RF exposure guidelines in the application process could lead to the preparation of a formal Environmental Assessment, possible Environmental Impact Statement and eventual rejection of an application. Technical guidelines for evaluating compliance with the FCC RF safety requirements can be found in the FCC"s OET Bulletin 65 (see "OET Safety Bulletins" listing elsewhere at this Web site).
The FDA, which has primary jurisdiction for investigating mobile phone safety, has stated that it cannot rule out the possibility of risk, but if such a risk exists, "it is probably small." Further, it has stated that, while there is no proof that cellular telephones can be harmful, concerned individuals can take various precautionary actions, including limiting conversations on hand-held cellular telephones and making greater use of telephones with hands-free kits where there is a greater separation distance between the user and the radiating antenna. The Web site for the FDA"s Center for Devices and Radiological Health provides further information on mobile phone safety: FDA Radiation-Emitting Products - Cell Phones.
The FCC does not normally investigate problems of electromagnetic interference from RF transmitters to medical devices. Some hospitals have policies, which limit the use of cell phones, due to concerns that sensitive medical equipment could be affected. The FDA"s Center for Devices and Radiological Health (CDRH) has primary jurisdiction for medical device regulation. FDA staff has monitored this potential problem and more information is available from the CDRH Web site: http://www.fda.gov/Radiation-EmittingProducts. (Back to Index)
Cellular wireless radio services transmit using frequencies between 824 and 894 megahertz (MHz). Transmitters in the Personal Communications Service (PCS) use frequencies in the range of 1850-1990 MHz. More recently, advanced wireless services have been or are being introduced that transmit at frequencies in the 600, 700, 800, 1695-1780, 1915-1920, 1995-2020, 2110-2200 MHz spectrum ranges. Antennas used for cellular and PCS transmissions are typically located on towers, water tanks or other elevated structures including rooftops and the sides of buildings. The combination of antennas and associated electronic equipment is referred to as a cellular or PCS "base station" or "cell site." Typical heights for free-standing base station towers or structures are 50-200 feet. A cellular base station may utilize several "omni-directional" antennas that look like poles, 10 to 15 feet in length, although these types of antennas are less common in urbanized areas.
At a given cell site, the total RF power that could be radiated by the antennas depends on the number of radio channels (transmitters) installed, the power of each transmitter, and the type of antenna. While it is theoretically possible for cell sites to radiate at very high power levels, the maximum power radiated in any direction usually does not exceed 500 watts.
As discussed above, radiofrequency emissions from antennas used for cellular and PCS transmissions result in exposure levels on the ground that are typically thousands of times below safety limits. These safety limits were adopted by the FCC based on the recommendations of expert organizations and endorsed by agencies of the Federal Government responsible for health and safety. Therefore, there is no reason to believe that such towers could constitute a potential health hazard to nearby residents or students.
Other antennas, such as those used for radio and television broadcast transmissions, use power levels that are generally much higher than those used for cellular and PCS antennas. Therefore, in some cases there could be a potential for higher levels of exposure to persons on the ground. However, all broadcast stations are required to demonstrate compliance with FCC safety guidelines, and ambient exposures to nearby persons from such stations are typically well below FCC safety limits.

Radio and television broadcast stations transmit their signals via RF electromagnetic waves. There are thousands of radio and TV stations on the air in the United States. Broadcast stations transmit at various RF frequencies, depending on the channel, ranging from about 540 kHz for AM radio up to about 700 MHz for UHF television stations. Frequencies for FM radio and VHF television lie in between these two extremes. Broadcast transmitter power levels range from less then a watt to more than 100,000 watts. Some of these transmission systems can be a significant source of RF energy in the local environment, so the FCC requires that broadcast stations submit evidence of compliance with FCC RF guidelines.
The amount of RF energy to which the public or workers might be exposed as a result of broadcast antennas depends on several factors, including the type of station, design characteristics of the antenna being used, power transmitted to the antenna, height of the antenna and distance from the antenna. Note that the power normally quoted for FM and TV broadcast transmitters is the "effective radiated power" or ERP not the actual transmitter power mentioned above. ERP is the transmitter power delivered to the antenna multiplied by the directivity or gain of the antenna. Since high gain antennas direct most of the RF energy toward the horizon and not toward the ground, high ERP transmission systems such as used for UHF-TV broadcast tend to have less ground level field intensity near the station than FM radio broadcast systems with lower ERP and gain values. Also, since energy at some frequencies is absorbed by the human body more readily than at other frequencies, both the frequency of the transmitted signal and its intensity is important. Calculations can be performed to predict what field intensity levels would exist at various distances from an antenna.
Antenna maintenance workers are occasionally required to climb antenna structures for such purposes as painting, repairs, or lamp replacement. Both the EPA and OSHA have reported that in such cases it is possible for a worker to be exposed to high levels of RF energy if work is performed on an active tower or in areas immediately surrounding a radiating antenna. Therefore, precautions should be taken to ensure that maintenance personnel are not exposed to unsafe RF fields. (Back to Index)
Land-mobile communications include a variety of communications systems, which require the use of portable and mobile RF transmitting sources. These systems operate in several frequency bands between about 30 and 1000 MHz. Radio systems used by the police and fire departments, radio paging services and business radio are a few examples of these communications systems. They have the advantage of providing communications links between various fixed and mobile locations.
There are essentially three types of RF transmitters associated with land-mobile systems: base-station transmitters, vehicle-mounted transmitters, and hand-held transmitters. The antennas and power levels used for these various transmitters are adapted for their specific purpose. For example, a base-station antenna must radiate its signal to a relatively large area, and therefore, its transmitter generally has to use higher power levels than a vehicle-mounted or hand-held radio transmitter. Although base-station antennas usually operate with higher power levels than other types of land-mobile antennas, they are normally inaccessible to the public since they must be mounted at significant heights above ground to provide for adequate signal coverage. Also, many of these antennas transmit only intermittently. For these reasons, base-station antennas are generally not of concern with regard to possible hazardous exposure of the public to RF radiation. Studies at rooftop locations have indicated that high-powered paging antennas may increase the potential for exposure to workers or others with access to such sites, e.g., maintenance personnel. This could be a concern especially when multiple transmitters are present. In such cases, restriction of access or other mitigation actions may be necessary.
Transmitting power levels for vehicle-mounted land-mobile antennas are generally less than those used by base-station antennas but higher than those used for hand-held units. Some manufacturers recommend that users and other nearby individuals maintain some minimum distance (e.g., 1 to 2 feet) from a vehicle-mounted antenna during transmission or mount the antenna in such a way as to provide maximum shielding for vehicle occupants. Studies have shown that this is probably a conservative precaution, particularly when the percentage of time an antenna is actually radiating is considered. Unlike cellular telephones, which transmit continuously during a call, two-way radios normally transmit only when the "push-to-talk" button is depressed. This significantly reduces exposure, and there is no evidence that there would be a safety hazard associated with exposure from vehicle-mounted, two-way antennas when the manufacturer"s recommendations are followed.
Hand-held "two-way" portable radios such as walkie-talkies are low-powered devices used to transmit and receive messages over relatively short distances. Because of the low power levels used, the intermittency of these transmissions ("push-to-talk"), and due to the fact that these radios are held away from the head, they should not expose users to RF energy in excess of safe limits. Although FCC rules do not require routine documentation of compliance with safety limits for push-to-talk two-way radios as it does for cellular and PCS phones (which transmit continuously during use and which are held against the head), most of these radios are tested and the resulting SAR data are available from the FCC’s Equipment Authorization database.

There are hundreds of thousands of amateur radio operators ("hams") worldwide. Amateur radio operators in the United States are licensed by the FCC. The Amateur Radio Service provides its members with the opportunity to communicate with persons all over the world and to provide valuable public service functions, such as making communications services available during disasters and emergencies. Like all FCC licensees, amateur radio operators are required to comply with the FCC"s guidelines for safe human exposure to RF fields. Under the FCC"s rules, amateur operators can transmit with power levels of up to 1500 watts. However, most operators use considerably less power than this maximum. Studies by the FCC and others have shown that most amateur radio transmitters would not normally expose persons to RF levels in excess of safety limits. This is primarily due to the relatively low operating powers used by most amateurs, the intermittent transmission characteristics typically used and the relative inaccessibility of most amateur antennas. As long as appropriate distances are maintained from amateur antennas, exposure of nearby persons should be well below safety limits.
To help ensure compliance of amateur radio facilities with RF exposure guidelines, both the FCC and American Radio Relay League (ARRL) have issued publications to assist operators in evaluating compliance for their stations. The FCC"s publication (Supplement B to OET Bulletin 65) can be viewed and downloaded elsewhere at this Web site (see "OET RF Safety Bulletins"). (Back to Index)
Radiofrequency warning or alerting signs should be used to provide information on the presence of RF radiation or to control exposure to RF radiation within a given area. Standard radiofrequency hazard warning signs are commercially available from several vendors. Appropriate signs should incorporate the format recommended by the Institute for Electrical and Electronics Engineers (IEEE) and as specified in the IEEE standard: IEEE Std C95.2-1999 (Web address: http://www.ieee.org). Guidance concerning the placement of signs can be found in the IEEE Standard: IEEE Std C95.7-2005 (available for free through the IEEE Get Program). When signs are used, meaningful information should be placed on the sign advising affected persons of: (1) the nature of the potential hazard (i.e., high RF fields), (2) how to avoid the potential hazard, and (3) whom to contact for additional information. In some cases, it may be appropriate to also provide instructions to direct individuals as to how to work safely in the RF environment of concern. Signs should be located prominently in areas that will be readily seen by those persons who may have access to an area where high RF fields are present. (Back to Index)
The Commission does not regulate exposure to emissions from these devices. Protecting the public from harmful radiation emissions from these consumer products is the responsibility of the U.S. Food and Drug Administration (FDA). Inquires should be directed to the FDA"s Center for Devices and Radiological Health (CDRH), and, specifically, to the CDRH Office of Compliance at (301) 594-4654. (Back to Index)
The FCC does not have a comprehensive, transmitter-specific database for all of the services it regulates. However, the FCC does have information for some services such as radio and television broadcast stations, and many larger antenna towers are required to register with the Antenna Structure Registration (ASR) database if they meet certain criteria. In those cases, location information is generally specified in terms of degrees, minutes, and seconds of latitude and longitude. In some services, licenses are allowed to utilize additional transmitters or to increase power without notifying the FCC. Other services are licensed by geographic area, such that the FCC has no knowledge concerning the actual number or location of transmitters within that geographic area.
OET has developed a Spectrum Utilization Study Software tool-set that can be used to create a Microsoft Access version of the individual exported licensing databases and then create MapInfo mid and mif files so that radio assignments can be plotted. This experimental software is used to conduct internal spectrum utilization studies needed in the rule-making process. While the FCC makes this software available to the public, no technical support is provided. (Back to Index)
By authority of the Radiation Control for Health and Safety Act of 1968, the Center for Devices and Radiological Health (CDRH) of the FDA develops performance standards for the emission of radiation from electronic products including X-ray equipment, other medical devices, television sets, microwave ovens, laser products and sunlamps. The CDRH established a product performance standard for microwave ovens in 1971 limiting the amount of RF leakage from ovens. However, the CDRH has not adopted performance standards for other RF-emitting products. The FDA is, however, the lead federal health agency in monitoring the latest research developments and advising other agencies with respect to the safety of RF-emitting products used by the public, such as cellular and PCS phones.
The EPA has, in the past, considered developing federal guidelines for public exposure to RF radiation. However, EPA activities related to RF safety and health are presently limited to advisory functions. For example, the EPA chairs an a Radiofrequency Interagency Working Group, which coordinates RF health-related activities among the various federal agencies with health or regulatory responsibilities in this area.
OSHA is part of the U.S. Department of Labor, and is responsible for protecting workers from exposure to hazardous chemical and physical agents. In 1971, OSHA issued a protection guide for exposure of workers to RF radiation [29 CFR 1910.97]. However, this guide was later ruled to be only advisory and not mandatory. Moreover, it was based on an earlier RF exposure standard that has now been revised. At the present time, OSHA uses the IEEE and/or FCC exposure guidelines for enforcement purposes under OSHA"s general duty clause (for more information see: www.osha.gov/SLTC/radiofrequencyradiation/).
In the United States, some local and state jurisdictions have also enacted rules and regulations pertaining to human exposure to RF energy. However, the Telecommunications Act of 1996 contained provisions relating to federal jurisdiction to regulate human exposure to RF emissions from certain transmitting devices. In particular, Section 704 of the Act states that, "No State or local government or instrumentality thereof may regulate the placement, construction, and modification of personal wireless service facilities on the basis of the environmental effects of radio frequency emissions to the extent that such facilities comply with the Commission"s regulations concerning such emissions." Further information on FCC policy with respect to facilities siting is available from the FCC"s Wireless Telecommunications Bureau (see https://www.fcc.gov/general/tower-and-antenna-siting) and from "A Local Government Official’s Guide to Transmitting Antenna RF Emission Safety."

It’s fantastic to have the top model of a car radio with a digital display in your car. You can see all the information you need regarding the music you are listening to, the navigation route you have to follow, and more.
As a general rule, your car radio display will not work if it encounters various issues like a blown fuse, the dimmer turned down, or a faulty illumination wire. The connectors between the LCD and radio unit could be wet or defective, or the backlight, LCD, or radio unit itself could be faulty.
Tip:The most common reason for car radios not working can be blown or defective fuse, or faulty illumination wires. If this is the reason in your case, you may need to start the repair by replacing the defective fuse in your stereo. Check out my favoritecar audio fuseson Amazon.com now.
Let’s look at why your car radio display won’t work and all the possible reasons that could impact it. These reasons are not always as dreadful as you may think, and most of them can be cured with little effort.
Today, car radios have come leaps and bounds from the heavy, mechanical, and manual radios of the 1950s that only offered an AM//FM stereo with frequency and volume knobs.
You could roll vintage car radio down a hill, and it would still be perfectly fine. However, if you have a cold and sneeze in the direction of your $500 Double Din aftermarket infotainment system, and it is not set up correctly, it won’t function.
If you find yourself in a predicament of your car radio’s display not working, you might feel a little inept at dealing with the situation; however, only a handful of variables can be wrong with it.
If you have not assumed it already, this will be one fix that you can apply to your car stereo and could cause the display screen not to turn on, and I will explain it in detail below.
When a fuse is blown, not only display does not work, but the whole radio does not function. If however, your radio works but the screen remains blank, you will need to consider a few other factors when determining why your car stereo display is not working correctly.
When your car stereo is new and you have a warranty, the easiest solution is to take the stereo to the retailer, and they will fix it. The more complicated situations are when your radio is older with the warranty expired.
Sometimes, the car stereo display is too bright, and when the radio does not have a day/night display function, most drivers including me, prefer to turn down the display brightness (especially at night).
If this doesn’t work, then there may be a problem with the illumination wire (it may be damaged or loose), and if you remove the radio and check the wiring, you will be looking for an orange or orange/black wire.
Your car radio is not one solid unit. This means that the display is separate from the actual radio unit, and wires and connectors are used to link them together.
If there are mechanical connectors (something similar to a harness) that are broken or damaged in any way, and you think this could be the cause of the problem, it may be possible to purchase those connectors from a repair shop. Otherwise, you will have to take it in and let them source the parts for you.
However, if the display is dimmed down and you still have power, then the first thing you should do is check your user manual and go through all the settings and presets that your radio offers to try to find brightness settings that could be used to adjust your radio back to normal.
Suppose you have already gone through all the steps and procedures that I have laid out for you, such as checking the dimmer, checking the illumination wire, checking settings and presets, trying to reset the radio, and checking the fuses. In that case, there may be an issue with one of three things with your car radio.
In a situation like this, the only option you have is to take it in for repair (if it can be repaired). Otherwise, if you have a service plan or an aftermarket radio with a warranty, you should be able to replace it without any hassles.
The main reason the car radio display may not be working is because of a bad fuse. I already touched on this briefly because it is the most common car stereo (radios) problem.
In older cars, the fuse would be placed on the radio, so you would have to take out the entire stereo to get to the back of it just to replace the fuse.
Sometimes this meant having to take off part or most of the dashboard. If this is the case for your car and stereo model, then this might be a hassle, and you may have to take it to an automotive repair shop.
Luckily with most modern cars, the car radio fuses are located in the fuse box with all the other fuses that are grouped together. Typically you can find this box on the dashboard close to the steering wheel or under the hood.
These names indicated which fuses are for which car parts and systems. You would need to look for the fuse (code) name that says either Room, Accessories, Interior Lights, or Radio and check if that fuse is blown and then replace it with a new one your car radio should work and display correctly.
You may be wondering why some of those code names don’t refer to the radio. Sometimes manufacturers have combined circuits in your vehicle, and the fuse used for your radio will also be used for your interior lights. In general, you should replace any fuse you will find that is blown.
If the short to ground has affected the circuit of the radio and caused a surge of current, then the fuse may be blown, and all you will have to do is follow the steps we laid out for you in the section above.
In the instance where your radio is still working, but there is no display, then one scenario could be that a setting or the dimmer was turned down all the way. In this case, you can try resetting your car radio to the factory settings.
This is slightly different from adjusting the dimmer and checking functions and settings on your car radio. Most radios, if not all due to their complicated nature, will have a reset button.
A reset button is usually found behind the removed faceplate of the radio. You will typically need something long and thin to get to the reset button, like a needle or a pen. Just remember that if you reset the radio, you will lose all saved data.
If you cleaned your screen with water and it still works, you are in luck. And the only thing you would need to do is make sure the connection point and wires that sit between your display and the radio unit are dry.
The better way to clean the car radio screen and especially a touch screen is to use a soft microfiber cloth and clean off any dirt, dust, or fingerprints on the screen.
Dirt or dust on the screen blocks its direct contact with your fingers, causing the touchscreen to be unresponsive. To avoid this, clean the screen regularly with a microfiber cloth and do not touch the screen with dirty hands.
