My wife was watching TV the other night and heard a loud pop before the set went dark. When I investigated it was blinking 10 times. However after a power cycle it went to the 4 blink sequence.
After poking around on the forum I wound up here and did some more troubleshooting. With power removed, I disconnected the SC card and it went to 7 blinks so I thought I was on the right track. However I reconnected power to SC after a bit and the power on blink was now 10.
That said, it's clear what happened to the SC card based on looking at things. Q403 was blown completely apart and the broken bit was laying flat on the board as can be seen in the attached photo. Not sure if the darkening on the adjacent part is due to it overheating or a result of the catastrophic failure of Q403.
I guess the question is if am I better off buying a used SC board or buying a repair kit? I've got reasonable soldering skills but probably not enough to do a bunch of surface mount items. Though I guess the best route for those, if needed, would be to use solder paste.
Had the set since 2010 and it's been flawless so I hate the thought of going to a cheap LED panel if this one can be saved.
