Fortunately, we have compiled a few tips to help you learn how to get rid of a blue screen on a TV.

What causes a Blue screen?

It is not uncommon to find that your TV has color distortion issues. For example, you can get the blue screen of death, which is why it is important to learn how to fix tv color distortion. There are several reasons why your TV has a blue screen. Additionally, a black screen on the TV can be caused by some of the same reasons as a blue screen but be sure to check out the article for tips on how to fix it. However, if you believe your TV has blown a fuse, a black screen is the most common symptom. The following are the most common causes of blue screens:

Improper Source Device Setup

Perhaps the most common reason why your TV screen is blue is that the source or input device has not been set up in the proper mode. For example, if your cable box is linked to your TV using a coaxial cable, your TV needs to be set to a program channel input to receive a signal and not a TV/Video input.

Video-Input Issues

A blue screen on your Television can indicate a problem with the TV/video input. If the issue fails to turn off, it could mean the TV’s internal memory is overcharged, or the power capacitors are faulty. However, if the TV screen turns blue and displays a “no signal” warning, it usually means the TV is set to the wrong video input.

T-Con board issues

A faulty T-Con board could lead to a blue screen. T-Con board issues could be as simple as a loose connection from the T-Con board to the panel or a malfunctioning T-Con board. It could also be due to a bad capacitor or a faulty power output from the panel to the T-Con board. A malfunctioned T-Con board will have a black or blank display.

Fixing a Blue Screen on your TV

The most probable reason why your TV has a blue screen is due to a connection issue. To determine the cause of the problem, do the following:

  1. First, unplug the TV from power for about 5 to 10 minutes, then plug it back in to see if the problem clears up. Your TV has processors, and like any other operating system, can crash. Unplugging it from the mains resets the microprocessor.
  2. Next, check the antenna connections, audio video, and HDMI cables. When there is a weak or no signal from a source device, your TV screen will shift to blue. A loose connection can cause a variety of issues with your TV. For instance, if you need to fix a sound delay on your TV one of the first things you should do is check the connections.
  3. Check your source device settings and make sure that all output settings are turned on. Then, try another source device to see if a blue screen still turns up.
  4. If you’ve tried all the above and still have a blue screen, you might need to check the TV hardware for faults. This often involves testing the power board voltage. If the power board is fine, you might need to replace your TV T-Con board.

It is essential to note that testing and replacing your power board or T-Con board requires technical know-how. If your TV has a warranty, send it in for repairs. After you are done fixing the TV, you can find out how to mount a tv on a wall for best performance. And if you are going to mount a tv to watch outside be sure to follow proper guidelines for safety.
