Quick Fixes

Try a few simple things first to try and fix your TV before replacing parts…

1 – Unplug TV overnight. Plug back in and SOMETIMES it may work and fix your issue.

2 – Unplugging the TV and everything hooked to it, then plugging it back in may clear the problem.

3 – Be sure the TV is set to the correct input. If it is set to DVI or Component input when it should be in the HDMI input this will cause issues.

------------------------------------------------------------------------------------------------------------------------------

If the 3 quick fix checks above do not resolve your issue, try this:

Press the TV menu button. If no menu appears the problem could be a bad tcon display board or backlight inverter board. Turn off the room light and check TV for backlight glow. If it has a glow then the problem can be a loose tcon connection or bad tcon board. Check connections.

Possible TV Back-Light Inverter Board Issue:

To see if the back-light has gone out, turn the TV on. Turn the lights off and make the room dark. Shine a flashlight onto the screen at different angles. If you can see some of the picture then the back-light has gone out. (It should glow a slight grey if it’s working) To fix this you need a TV backlight inverter board. '''You can buy one online for a relatively low price. Usually the board will have a few bad capacitors on it. You could attempt to repair it yourself if you can identify which capacitor has gone bad. A capacitor kit for a TV board is ultra cheap. You are best off buying the backlight inverter board and installing it yourself. A back-light inverter board should be from $10 to $25 dollars depending on your TV model.
