Loud bang, unit stopped working

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.

Samsung plasma tv about 6 years old turns off immediately after turning on

Oh yeah!
Did you have to play with "power button" or trying to squish your "clicker" before set went down south?
Probably-yes? Or, have heard loud bang? May be. may be not?
Have your TV was loosing picture or shutting off due to regular usage? If you answered 'yes" at least twice, you need to surrender your efforts to specialists!
There is nothing you can do to revive your "baby", unless you know where to look and what to do next! Diagnostics of Plasma is a "Top Gun" of skills: it will shut down for any reason, when "brain computer" detects a fault! Plasma TV has a dozen of power supplies, plus "sustainers" and "buffers" which are subject of high voltage and high current circuitry. Therefore, those are guarded well by "shut down" system. Each independent power supply is under constant monitoring, to prevent major overload and possibly structural damage of display itself. 6 years old is enough to accumulate multiple troubles. But the first one , which was ignored or considered "self healing" killed your set! not literally, but at this particular condition. Please: don't even dare to open TV, unless you are the semi-pro! You must start from the very beginning , usually power supply, and if that's not a case(bet, you'll find bloated capacitor), then proceed to check sustains fuses and bloated large capacitors. If you see them bloated and any fuse is open(ceramic ones), STOP right there!
Or, call local reputable repair shop.

Loud buzzing noise

Mine is loud also when playing games. When playing DVD's it is not. I think it is a factory defect on some of the systems. I would not attempt to pull apart the DVD drive and try and fix it. It is working and on an XBOX 360 you should feel lucky that it is.

Plasma TV, loud bang, dead screen

I have a Sony KE-32TS2 set. We heard a very loud bang, and the screen is dead. We still have audio and the ability to change channels. One electrician friend suggested a blown capacitor in the powersupply. I'm pretty handy with electronic repair. Can I do this myself?

Loud clicking, banging noise

No Picutre

someone shot your tv.





no really, I am just a smart a$$ --- but the loud pop sounds like it may have been one of the capacitors in the power supply board. check for a POPPED cap (rare) and if there is one, test the components in the related circuit - as SOMETHING had to happen to make a cap fail like that - maybe a voltage regulator? give it a look..

Sound shuts off, sub still works

That is a common problem with this radio, for it can not go to loud without going down in volume or shutting down.
