Sometimes it turns out that on pressing the power button on your TV you"re not getting a picture and a sound. The first thing you are to determine whether it is a TV issue or a power issue. To check if power is supplied to the TV unplug the power cord from the back of the TV or the wall outlet. While it is unplugged, disconnect all external devices from the TV.
Hold pressed a power button on the TV for several seconds. Reconnect the power cord. Then, as you press the power button, look at the LED power indicator light. If it is not lighting up at all unplug the power cord from the TV and from the wall outlet and securely and tightly plug it back in.
Verify if the surge protector or an extension is turned on in case a power cord is connected to these devices. If a TV screen appears black, plug another device into the socket to check whether this device is getting power from the outlet. If power is supplied to the outlet it means that your TV is powering on and a picture issue should be revised. You need to make a call to the TUSA Service Center and our technician will soon revive your TV.
There are many possible problems in case your TV is powered but a TV screen goes black and there is no sound. All you can do in this case at home is to reset your TV to the factory defaults. This procedure is described in the User Manual of your TV.
To double-check this failure press a MENU button installed on the TV to see if TV´s MENU appears on the screen, In case the MENU appears, verify that all video connections are well secured and to appropriate jacks on your TV. If the result is negative, you can trigger the MENU to reset your TV to the factory defaults.
Highlight YES and press “ENTER”. The TV will turn off automatically after a few seconds. After the TV turns off, unplug the TV power cord and then plug it in again to complete the reset process.
In case neither of the above steps resolved the problem of the TV, you are welcome to get urgent assistance with this problem by contacting the TUSA Service Center.
Sometimes when watching TV, annoying situations arise when a TV screen fades off to black. That is to say, the TV screen goes black at random times and appears to be off but the sound is available and the power light is still illuminating. A troubleshooting procedure may differ for a variety of TV brands but generally will work the same to fix the problem and is as the following:
Use a different HDMI port for the device you are using. Unplug the HDMI from one input and plug it to a different input to test if a port is bad. Checking and reconnecting HDMI cable on the back of your TV along with switching the inputs to BLU-RAY and CABLE may lead to the expected positive result.
Connect a different device to the TV or the same device to another TV. The device being used (Ex. Blu-Ray/CABLE BOX) may cause the black screen issue.
Turn the device (Ex. Blu-Ray/CABLE BOX) you are using OFF and then back ON. The device you are using may have a temporary fault and needs to be reset.
A hidden fault within HDMI cable – Replace with new High-Speed HDMI 2.0 cable. Replace the HDMI cable as it may have a short or another defect which causes the black screen issue.
Suddenly, a black screen on your TV is commonly referred to as a «death screen» - having seen this, every owner thinks that it is likely that he will have to buy a new technique. But not always the black screen is an irreparable breakdown, quite often the cause can be eliminated on its own.
So, you were watching your TV when the screen suddenly turned suddenly black or started slowly blackening and then completely faded. What can be done yourself before contacting a dedicated repair service center?
Carry out the sound test. To do this, turn on the TV and listen carefully - do you hear any characteristic sounds that would allow you to judge the operation of the equipment?
A light test should then be carried out. Direct the home flashlight beam to the screen of the TV on - if you see an image, the problem is that one of the panels of the TV has failed.
The next step is to check the cable and power connections. Sometimes the solution to the problem lies in the simplest step - perhaps your TV simply has contacts on connected wires. If all wires are connected, try to disconnect the TV completely from the network, restart the hardware, and re-enable it.
Based on this information, it will be easier for the wizard to understand what the problem is and what is the probability of quickly correcting the problem on your TV.
Many users of modern television equipment face such a problem as sudden handwriting of the screen and then restoration of its operability. What to do in that case and what can it come from? If you do not want to tolerate any more interference in the form of a sudden black screen on your TV - it is better to contact the specialists of the service center immediately. But before the wizard arrives, try all of the above - check the TV for an audio signal at the time of activation, test with a home flashlight, and make sure to check all power and wire contacts. Perhaps you can set up the equipment before the specialist arrives.
You see various blinks while watching television channels. At the same time, viewing various Internet services or videos from the flash, does not cause complaints. This kind of problem is directly related to the incorrectly installed antenna. Try to set up your device so that you are as comfortable as possible to watch TV channels.
Perhaps after connecting USB drives and other portable devices, your TV screen starts blinking. Often, such a fault can be related to the failure of ports and connectors. In most cases, you can solve the problem yourself or by contacting the service center. If you have the tools you need, you can detach a specific port and replace it with a new part.
There is only one way out of this situation - you should contact the service center to help you cope with the problem. Experienced qualified masters will come to the specified address in any area of the city, perform diagnostic works with the help of specialized equipment and eliminate the problem directly on the day of circulation. Available prices, warranty for completed works and prompt departure to the client are the main advantages of calling the TV repair master to the house.
In case you need to deliver a faulty TV to the service center, the wizard will do so independently. After all necessary works on the basis of the service center, the TV will be delivered to you at home and you will be able to use serviceable equipment.
After a long, hard day, you finally sit down to catch up on your favorite show. But when you hit the power button on your remote control, your TV screen stays black! You try pressing the remote’s power button again and again from every angle, but still, your TV has no picture. If this sounds familiar, you’ve likely fallen victim to one or more TV screen issues.
What causes a TV screen to go black? Software issues, loose connections, or backlight problems are usually behind black TV screens. Learn about each of these causes and get tips for troubleshooting them so you can get back to relaxing with your favorite TV shows, movies, and video games.
If your TV screen is black and there’s no sound, you’ll want to check for an LED light or a small indicator light that tells you the TV has power. If there is no power to the TV while it is plugged in, there may be an issue with the outlet or fuse box in your home. However, if the TV is on but the screen is black, the problem could lie with your TV’s software.
Unplug the TV from the wall, and, if possible, remove the power cord from the back of the TV to perform a soft reset. Wait 30 seconds, and plug the TV back into a working outlet to test it again. If you’re still having screen issues, you might want to bring in an expert — they’ll know how to fix your TV’s black screen.
If your TV screen goes black but the sound still works, the first thing to check is the input source to ensure it is turned on and operating correctly. This includes external devices like cable boxes, video game consoles, laptops, and streaming devices. Once you’re sure the input source is working properly and you have the right input settings, check the cable connections. In many instances where the TV screen is black but the audio works, poor cable connections could be the issue.
Whether you’re working with an HDMI cable, RCA (usually yellow, white, and red cables) set up, or another type of connection, you need to ensure the cables are seated properly and firmly into their connection ports. With a good connection, the cable shouldn’t feel loose or easily disconnect when pulled on or moved around. If all your cables have a snug fit but the problem persists, try connecting the device to another TV. If your TV screen is still blacked out, you may need new cables.
Some TV displays, such as LCD screens, use a backlight to illuminate the picture. If the backlight burns out or stops working, it will result in a blank TV screen.
To check your TV’s backlight, make sure your TV is on. Then, turn off the lights in the room and shine a flashlight on the screen. If you can see a picture with the flashlight, then your TV’s backlight is likely burnt out.
While you might be eager to learn how to fix a black-screen TV, a broken backlight does not come with an easy solution. The backlight will need to be replaced, and it’s best to get help from a professional with this task.

Mobile operating systems have their own versions of the black screen of death. Apple"s iOS users might need to force-reset their devices, though the method differs depending on the model. For owners of the iPhone 8 or newer models, press and let go of the volume-up and do the same to the volume-down button, then press and hold the side button until you see the Apple logo. For those with the seventh-generation iPod or iPhone 7, hold the top or side button and the volume-down button until you see the logo.
iPad models equipped with Face ID should press and release volume-up, then volume-down, and then hold down the top button. For those with iPads with a home button, iPhone 6s or older devices, or iPod touch sixth generation or older, hold down the side or top button and the home button together until you see Apple"s logo, which should take at least 10 seconds to appear.
Android device users should start by holding down the power button on your device for five to seven seconds, which should restart it. If the device hasn"t been charged, there might be a problem with its power cord, adapter, or even the electrical outlet. If the device has power, you may have a problem with the screen. It may seem strange that you can receive calls on an Android device with a black screen. If this happens to you, hold down the power button for 30 seconds, then let it go. Don"t touch the power button again for two minutes, after which call it or use Find My Device to see if it will ring. Before you take it to the repair shop, consider resetting your device to its factory settings to determine if the screen is truly broken or if there"s an error in the operating system.
Regardless of the device and the reasons behind the black screen of death on your system, if it"s a recurring problem, it"s a good idea to have a professional take a look at it to make sure there isn"t an issue that may spell the loss of your data and perhaps even your device.
If you have a black screen, before you move on to any of the suggestions listed, check the most obvious first: Is the battery on your device charged or dead? If it"s dead, that"s the cause of your black screen. To solve, plug it in!
Ever had your TV showing nothing but a black screen even if the audio was working? Unfortunately, that’s a common issue with low/middle-end LCD/LED TVs these days… Even more frustrating, this issue often comes from a rather tiny and cheap component that can be easily replaced. Most common issues are:
One of my relatives had this exact symptom happening all of a sudden. This problem on low-end TVs often occurs within the first couple years. As the repair costs for that kind of TV is pretty low, considering repairing it yourself might be a good idea!
The first step into repair is to find the root cause of the issue. As backlight failure is a very common issue, this is the first thing to test. To do so, the easiest way is to power on your screen, put a flashlight very close to it and check if you can see the image through. The image would be very dark, like turning the brightness of the screen very very low.
That implies disassembling the TV to access the backlight which is between the LCD screen in the front and the boards in the rear. In my case, with a Samsung F5000, I had to process as follows:
First we have to remove the back housing to reveal the boards (from left to right: main board, T-CON, power supply) and disconnect the LCD panel from the T-CON board.
Note: Older TVs have neon tubes for backlight, which is thicker and less exposed to this kind of failure. LED backlight is the most common thing these days, but do not mistake an LED TV with an OLED TV. The first one is a classic LCD panel with a LED backlight, whereas the second is an OLED panel that doesn’t need any backlight as it is integrated in each pixels (making the spare parts much more expensive by the way).
As we can see, the backlight system is made of 5 LED strips. First thing to do is look for burnt LEDs. Most LED backlight systems have strips set in series, meaning that if one of the them fails, all the system goes dark…
Using a multimeter, we can confirm that the strips are indeed set in series, so now we have to test each strip individually. Professionals use LED testers such as this one (about 40$ on amazon) but as I didn’t had one at the time, I decided to make one, McGyver style!
