LED LCD screens do not easily need repairs but it does then need good care. LED LCD screen contains quite a number of layers which include a color filter, TFT sheets, liquid crystal, and a second polarizing filter. There could be many possible reasons and different symptoms of TV’s screen being non-workable. Following are the causes and solutions to them:

1.    White Screen: There are situations where you could find a completely white screen on the TV which clearly indicates that the LED LCD repairer needs to focus on PSU. You will have to check each electrolytic capacitor on PSU. Check the fuses. There is the only place where the problem lies while in the situation of the white screen. 

2.    Rainbow screen: While seeing a rainbow screen on a TV, the first thing you need to check or replace is the LVDS cable. Checking the solder connections and FPCB.

This somehow will solve the problem but if the problem still continues, we need to go deep on this topic and as a trainer would help you with that.

3.    Flash and shut: There is a situation where televisions often flash and shut down immediately this can be caused by the failure of the inverter board.

4.    No backlight: There is often a time when everything seems normal on the TV except one thing that usually not everyone can figure out. You could see the screen a little illuminated or the colors may seem different, it is because there is no backlight on your television screen. For this situation, you can check the PSU.

5.    Lines on screen: Whenever you see any kind of line on the display, whether it is horizontal or vertical, it is clear that there is a connection problem from the driver to the board panel. In this situation, it is the easier way to replace the whole screen or one may work on troubleshooting over the panels.

6.    Cracked screen: In the cracked screen, there is no other option than to replace the screen. Nothing could be done to repair it because the cracked panel has destroyed the screen deeply and replacing it would be the only option left.
