5 Causes of a White TV Screen
If your TV screen has suddenly turned white, don’t panic. There are a few possible issues that could be causing the problem, many of which you may be able to fix yourself.
Here are 5 common causes for a white TV screen and how to resolve them:
1. Faulty cables or connections
Loose or damaged cables are often the culprit.
Double check that all cables connecting your devices are securely plugged in. If any look visibly frayed or damaged, replace them.
HDMI and power cables in particular can cause issues if not properly connected.
2. Incorrect input selection
Make sure you have the correct input source selected on your TV. You’ll get a blank screen if it’s set to HDMI 1 but your streaming device is plugged into HDMI 2.
Use your remote to cycle through the inputs until an image appears.
3. Malfunctioning power supply
If the power supply providing juice to your TV is on the fritz, it may result in a white screen.
Try unplugging the TV for a few minutes to reset it. If that doesn’t work, the power supply itself likely needs service or replacement.
Call a tech for help diagnosing and replacing the faulty component.
4. Damaged backlight
The backlight provides illumination for the TV display. If it’s damaged or burned out, the screen will appear very dim, dark, or white.
Unfortunately, a bad backlight typically requires repair or replacement by a technician.
5. Broken LCD panel
An LCD panel is responsible for displaying images on your TV screen.
If the panel is cracked or otherwise broken, it won’t be able to properly show visuals, resulting in a blank white screen.
Like a faulty backlight, a broken LCD panel will need professional service.
How to Fix a White TV Screen
If your TV screen has suddenly turned white, don’t panic. There are a few possible fixes you can try before calling a technician.
Check your input sources
The problem could be with your input source. Try cycling through the inputs on your TV to make sure there isn’t an issue with the HDMI cable or other input device.
If the white screen goes away on a different input, you’ll need to troubleshoot that device.
Reset your TV
It’s possible there’s an internal software glitch causing the issue. Try doing a “hard reset” of your TV by unplugging the power cable for a few minutes to allow it to fully shut down.
Then plug it back in, turn on your TV and see if the white screen is gone.
If that doesn’t work, you may need to do a “factory reset” of your TV’s software in the settings menu.
Make sure you don’t have any valuable settings you need to backup first.
Check for loose cable connections
Loose or damaged cables are a common culprit for display issues. Ensure all video input and power cables are securely connected to your TV and any devices.
If possible, try swapping out HDMI or other input cables to rule out a cable problem.
Let your TV cool down
If your TV was recently moved or the vents were blocked, it’s possible it overheated which can sometimes cause temporary display issues.
Leave your TV unplugged for a couple of hours so it can cool down completely. Plug it back in and turn it on to see if the white screen is resolved.
Have a technician check for physical damage
If all else fails, it’s best to have a TV technician evaluate your set.
They can properly diagnose if there are any physical issues with the display panel or internal components and perform necessary repairs to get your TV working again.
So there you have it, some of the most common reasons why your TV screen went white.
Don’t lose hope – in many cases, the problem is fixable if you’re willing to troubleshoot or call in a technician.
At the very least, now you have a better sense of what could be causing the issue and what to try next.
Hang in there and keep working through the possible solutions.
If only part of your TV screen is white, it could indicate a problem with the LCD panel or backlight. The LCD panel contains millions of tiny pixels that create the images on your screen. If some of these pixels become stuck in the ‘on’ position, they’ll appear white. Issues with the backlight, which illuminates the LCD panel, can also cause white spots or patches.
In these cases, it’s best to have the TV serviced by a professional. They have the proper tools and parts to diagnose and repair issues with the LCD panel or backlight. Attempting to fix it yourself could easily make the problem worse and void your warranty.
