Hi @randall0522 ,
If you can’t see any images on the screen when there is audio and you’re shining a torch at an angle close to the screen then there is more than just a backlight problem.
Can you view the TV menu screens OK?
Have you tried using a different input or input type e.g. HDMI, Component video etc or even a different signal source e.g. a dvd player to see if there are any images at all?
It is good to check the voltages on the power board to prove that it is OK but with no images and no backlights and changing inputs/sources etc makes no difference, it appears to be a mainboard problem
If you can see any images on the screen when there is audio and you’re shining a torch at an angle close to the screen then as you say there is a backlight problem. You will need to check that the backlights are getting the correct voltage from the power board
