It would be more helpful to open up a separate inquiry. Please include the model number of the TV as well.

Thanks,

There are a number of possibilities, but additional information is required:

1) When you turn on the TV, does the standby light blink? If so, is there a pattern? How many blinks?

2) With the TV on, use a flashlight at an angle, can you see the picture on the screen?

3) Model number of the TV?

Thanks,

Dan

With sound, the back light may not be working. To confirm this, use a flashlight at an angle toward the screen. If you can see the picture on the screen, then the back light is not working. This can be as simple as a bad capacitor on the power board or perhaps a failed LED strip or LED. Please provide the model number of your set so we can post more specific things to check. Also, if you can, post a few pictures of the boards once you have opened up the back.
