dark lcd screen problem quotation

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…

For starters I’ll go with the third one, just to make sure there is no other issues with the TV, but afterwards it’s better to replace the LED with a new one, otherwise you might notice a darker spot on the image.

There might be a lot of other root causes for similar symptoms, a black screen often looks like something very serious and therefore expensive to repair, but this case is the perfect example that taking some time to look for the root cause can sometime lead to a good surprise: here a 1$ fix!

There are tab connectors along the top of the TV that connect the tcon board to the LCD panel. These connections are very fragile but usually when they disconnect from the panel there are vertical black lines not just a darkening and also not over such a wide area. The TAB connector boards can be seen in the image that you posted where the 4 flex cables from the tcon board connect to them. Try cleaning and reseating the contact ends of the 2 flex cables, (both ends) that go from the tcon to the TABs on the side where the dimming is, just in case they have come loose during transit etc

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?

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.

If none of the above has helped you deal with the problem yourself - you should call the wizard at the service center and report the defect. During the consultation process, you should tell the master about the tests carried out and their results.

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.

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.

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.

Stable blinks of the display, if there are no problems listed above, can be caused by breakage of the power supply or communication wires. In particular, such a problem is often found in liquid crystal TVs.

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.

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!

Amongst all the challenges of remote working, an extremely frustrating one is not having immediate IT support available, which results in unnecessary stress, delays, and problems. Taking the laptop to the office to get it checked is a time consuming and inconvenient process, so some firms are remotely accessing their employees’ laptops to monitor their progress and fix any IT related issue. However, getting a hold of the IT department to ask them to take remote access and fix the issue is also inefficient as it wastes time, and even then, there is no guarantee that the problem will be fixed.

Imagine logging in to your laptop to attend a mandatory ZOOM meeting but only coming across a full black screen. Or suppose you are almost done with a project, but before you click ‘Save,’ the screen goes black. You would have a mini heart attack. You don’t know if your work is safe or when you will be able to deliver it. You are sitting there helpless desperation, with nothing but a bunch of questions.

Another issue for the screen going black is overheating. Overheating can cause your laptop to shut down when it overheats, or it may only turn off the display by cutting off power to the GPU (graphic processing unit). Your laptop might be overheating because of dust and debris build-up on the fan, heat vents, or sink. Get your laptop cleaned by a professional to resolve this issue.

Even if your screen is black, listen carefully to see if your laptop is making any booting sounds. However, this is only possible if you have a computer with a traditional hard drive instead of a newer computer model with an SSD and no other drives as they are silent during a normal boot.

If your laptop boots up fine, but the screen instantly goes black or blank after you log in, then there may be some issue with its operating system. An indication that the operating system is not loading properly or has a fault is that the screen will be blank except for the mouse cursor. One of the causes may be a corrupt system file that may be preventing the operating system from loading. Restart your computer to see if it is a temporary issue that can be resolved with a reboot. However, if the issue is still there, then erase your hard drive or reinstall Windows.

An issue with the graphics card can also cause a black screen. Connect a monitor or some other type of display to the laptop. If the external display works fine, then there is an issue with your laptop’s display. However, if the external monitor also doesn’t work, then either the cable is defective, or you need to get the motherboard or graphics card replaced.

If the screen’s picture is only partially visible, check to see if the laptop’s brightness is set to low or is being turned to a low because of a power-saving setting. Plug your laptop on for charging to make sure your laptop is not in the power saving mode; if not, try increasing the brightness.

Take your laptop to a reliable repair shop or call an expert to investigate and fix whatever the issue maybe that is causing your laptop screen to go black.

As often as you use your smartphone, it’s almost inevitable that you’ll eventually drop it. You may be extremely careful, but it only takes one fumble for your phone to tumble. While iPhone screens are designed to withstand impact, you might still end up with a shattered screen.

The good news: a broken screen doesn’t mean your phone is kaput. In fact, if only the glass is broken, the fix is quick and inexpensive. The bad news: if the LCD screen is broken, you’re looking at a pricier repair.

If you’ve looked into replacement parts, you’ve likely come across two very different options: a glass screen, and an LCD screen. While the first option is cheap, the second is definitely not. Here’s the difference:

1. The glass screen is the exterior layer on your phone’s display. While it is specially engineered for durability, it’s still just glass (between layers of plastic film), which is why it’s not very pricey to replace.

Most of the time, the damage to your screen will be pretty obvious. You’ll see the spider web patterns of shattered glass across the front of your iPhone. Occasionally, however, the glass screen will be intact, and you might not realize the damage until you try to use it. Whether the damage is visible or not, it’s a good idea to run a quick diagnostic to determine the extent of it.

If you encounter any of these problems, you’re dealing with a broken LCD screen. If the glass is shattered, but the display is clear and touch capability is working, that’s a good sign. The problem is probably just the glass screen.

Whether you’re dealing with cracked glass or a broken LCD screen, you can find a quick, reliable repair service at FastPhoneRepair.com. Our qualified technicians will get your iPhone repaired and up and running again in record time and at reasonable rates.

It means that, instead of the default dark text showing up against a light screen (known as ‘light mode’), a light colour text (white or grey) is presented against a dark or black screen.

The idea behind dark mode is that it reduces the light emitted by device screens while maintaining the minimum colour contrast ratios required for readability.

Dark mode is nothing new. If you’re old enough to remember Teletext and Ceefax, you’ll recall cyan or yellow text on a black background as you squinted at the TV to read the weather forecast.

Computers screens originally used what we now call dark mode, because of the capacities of the cathode-ray tubes used several decades ago. But in a bid to encourage people who weren’t programmers to use computers, interfaces were gradually adapted to resemble paper – i.e. black text on white paper.

The science behind dark mode is still a little shady, with lots of conflicting views and evidence as to its benefits. Some experts say it’s easier and healthier to read text against a dark background as it reduces eye strain, while other studies arrive at the opposite conclusion.

Many mobile users simply think dark mode looks more slick. And some apps, most noticeably Spotify, have always leaned to the shadier side of the colour spectrum.

You can also turn on dark mode from the control centre. To do this open the control centre, touch and hold the brightness control, then tap dark mode on or dark mode off.

If you have a phone with an older LCD screen, dark mode won’t really save your battery. You will need a OLED (organic light-emitting diode) screen for this to be the case.

Ultimately, opinions remain split on dark mode. But, until we know for sure whether it reduces strain on your eyes at night and helps promote sleep, at least there is the option of leaving your phone outside your bedroom.

My friend"s Olympus isn"t working... the LCD screen stays black (you can see the menus, etc., just fine, but doesn"t display image), viewfinder doesn"t work, won"t take photos (yes, the lens cap is off!).

Remove the lens. Switch the camera on. Obviously you see no picture, but it should display something, and it should display the difference between light and dark.
