what causes lcd screen to go black in stock

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.

A black screen on an Android can be frustrating. If you can tell your Android phone is on, but the screen is black and won"t respond, there are a few things you can do that might get it working again.

Make sure the buttons on your device are not jammed. First, inspect the buttons to be sure they"re not caked with dirt, lotion, lint, or other debris. Then try freeing the buttons by pressing the button several times in quick successions. The button should free depress and release with each press.

Inspect and clean the charging port. Dust and debris could keep your phone from charging properly. Inspect and clean the charging port. If necessary you can gently blow into the charging port, or use a wooden toothpick to try to remove anything that"s stuck in the port. Once it"s clean, plug your phone in and let it charge for about 10 minutes. After it"s charged for a short while, try restarting the phone.

Wait until the batteries die completely and the phone shuts down and then recharge the phone, and restart it after it"s fully charged. If there is a critical system error causing the black screen, this should get your phone working again.

Gently, but firmly press your phone from both sides, squeezing the front and back together. If there"s a loose LCD connection, this could help reseat the connection and get the screen working again. If this works, consider taking the phone to an authorized service center to have them firmly reseat the LCD cable.

If your phone is in a case, remove it from the case before you start this process so that you can accurately gauge how much pressure to put on your phone without breaking the screen.

Force restart the phone. Many critical system errors can be cleared up with a force restart. Depending on the model Android phone you have you may need to use some combination of buttons to force restart the phone, including:

Plug in phone, wait five minutes, and then try to do a Force Restart. This ensure the phone has enough power to restart, and restarting could clear any errors that might be affecting the screen.

If possible, remove the battery, wait 30 seconds or more, and then reinstall the battery and start your phone. If cannot remove the battery from your phone, you"ll need to allow your phone to discharge completely. Then recharge it and try to restart the phone again.

Use caution when taking your phone apart to remove the battery. If you have a newer phone that"s hard to open with the appropriate tools, take the device to a professional who can help. Otherwise, you run the risk of doing further damage to your phone.

If you have one, remove the stylus and see if it causes the screen to come on. If it does, navigate to Settings > General management > Reset and then choose Auto Restart and schedule a time for your phone to restart. You"ll have to wait until this time to see if an automatic restart fixes your problem.

Alternatively, you could also choose Factory data reset from the screen to completely reset your phone back to factory specs. This can be useful if you"ve installed a corrupt app that is affecting your display.

Choosing Factory data reset will delete all the data, including pictures, music, etc., from your phone, so if possible, back up your Android phone so you can restore your data once the phone is working properly.

If you have a Samsung phone, use the Samsung Smart Switch to connect your phone to your computer, and then try to access it, reboot it, or back it up from there.

Reboot your phone into Safe mode. Safe mode may allow you to navigate the phone to restart it, clear the cache (more on that below), or perform other tasks that could help fix the black screen problem.

When changing up which buttons you"re holding, you may have to try a few times to get the timing exactly right. It should be about 10 seconds before you switch to the new buttons (but keep the power button depressed all the time), but switching too soon or too late will cause the phone not to boot into Recovery Mode.

Clear the cache on your Android phone. This deletes temporary files and frees resources, which could resolve whatever issue is preventing the display from turning on.

Try a factory data reset. This will restore the phone to factory settings, which deletes all your data, so be sure you have a backup of anything you don"t want to lose before you start this process, if possible.

To restart your Android device, hold down the power button for several seconds and select Restart from the menu that appears. If that doesn’t work, do a hard restart by holding down both the power and volume up buttons for up to 20 seconds.

Android is known for its vast array of brands and models, spanning all budgets. Our favorites are the Samsung Galaxy Note20 Ultra and Google Pixel 4a 5G.

Overall, iPhones are of better quality than Android phones. A premium-priced Android phone is about as good as the iPhone, but cheaper Androids are prone to issues. Android phones surpass the iPhone in several categories, like battery life and voice assistant—it’s all about the features that are most important to you.

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!
