Question about Sony FWD-50PX2 50 in. Plasma Television
While playing Xbox, our Sony plasma suddenly let out a loud "bang" and went to black. Efforts to shut everything off have resulted in the green indicator light coming on for a short period of time, several "clicking" type noises and then a steady (not blinking) red indicator light and no action on the unit's screen -- totally black. Any suggestions/ideas for what could have blown out or otherwise happened? Thank you.
I have seen the caps in the power supply vent, which means they get hot and the top pops up and splits open, resulting in the "bang" sound. If you have experience in electronics then remove the back of the set and examine the power supply, looking for any caps whose tops are bowed upward, and replace.

My Sony FWD-42pv1 had a similar failure, but no loud bang, just a click off. When trying to turn it on after that, the green LED would come on for a few seconds, then blink off, then repeat a few times, before finally just giving up and going to solid red.
The problem turned out to be a failed Y-SUS board. The fuse on that board was blown, and the board had also failed (replacing the fuse wasn't enough). With a new board, the TV is running fine.
