My SV320XVT screen started flickering, intermittent at first and then slowly got worse until it was unwatchable. I did some research and figured it was the backlight inverter.
I opened the TV up, and while measuring the output on pin 13 of CN4 on the power board, I, er, kinda let the probe from my multimeter touch the live heatsink just below it and POP - GFCI tripped and now no backlight or picture.
I got the new inverter today and installed, and naturally that didn't fix anything due to the short.
Picture of the power board is attached
Unit can be switched from standby to on (vizio lights up from yellow to white)
No visibly damaged components
Fuse F1 reads 0 ohms while tv power is disconnected
Now, despite my being a total dumbass:
1. is there a way to isolate the problem on the power board I have?
2. should I just pop for a new board?
3. Did I just totally fry the TV and should just go ahead and part it out?
Thanks very much in advance.
