I started this journey here with what I thought were bad / shorted caps on the inverter board: https://www.badcaps.net/forum/showthread.php?t=28489
Hopefully my notes here can help someone in the future with their TV. As I note in the post, it looked like the capacitor shorted against the inverter transformer and went bad.
What actually happened was a CCFL tube went bad and it seems like that caused the voltage to find a place to go, eg the cap.
Fast forward to me disassembling the whole device; it finally occurred to me to check the CCFLs - the 5th one up from the bottom doesn't light.
At this point, I have a totally dissasembled TV, two good power boards (bought one trying to test), and all the other boards are good. I'd like to use the TV without spending much more money on it (after seeing the 720mm replacement CCFLs cost $20 + shipping I'm not sure).
Does anyone have a suggestion to get this running again? If there's a way to run without the bad tube I'd be willing to try it.
Thanks again!
