Hello, I have a Plasma TV I aquired for free and am not positive how to diagnose this. I checked all the fuses for continuity and they were good. No capacitors look bad.
When I turn the TV on, I get the power on sound, but the screen never updates, it remains the same grayish color as when it is turned off. I looked close to see if maybe the backlight was out, but it still did not look like it was displaying.
I watched a video and it suggested maybe the Y Sustain, or the logic board.
How would I go about confirming which board has failed, and if possible, which component?
