Another possibility is the audio section of the plasma tv which will be energized even though you are routing the audio through an independent sound system. Of course, if the plasma is a monitor only there is no audio section. Give that plasma a sniff. Easy for reflected sound to fool us into thinking it came from a different location from the origin.
What went bang, smelled of "I'm fried", yet left it in working order...???
Hi gang - wasn't sure if this should go here under amps or tech talk, but here goes: normally, I'd call the salesman I work with at my LAD, but they're closed Sun. & Mon. and I'm loosing sleep over this as I feel I'm on very thin ice.
My wife and I were watching a movie late last night, and after the movie we were sitting on the coach discussing it when we both jumped when we heard a loud bang coming from the media console and smelled an electrical burn. Sitting on top of the console is a Dan D'Agostino Progression Stereo power amp, a McIntosh C53 preamp, and mounted directly behind this on the wall, a Panasonic plasma TV.
Nothing tripped a fuse, the TV was still on, both sets of power meters on both the Dan & Mac were still lit. I streamed a test track that has a lot of bass that when I turn up to a certain volume, has the Dan's power meters hang at 400 watts for a few seconds, and they did - just like always. Everything seems to look and sound fine.
So, while I'm not asking for anyone to try and guess which of those three components made the bang, what I am asking is for any of you here who have an electronics background tell me what electronic part (in either the preamp, amp or TV) possibly could have made a loud bang releasing an electrical burn smell, yet "seemingly" leave everything still functioning as normal...?
--thanks and cheers!

@closenplay Thanks - I didn't smell anything around the plasma, but I'll check out the audio section on the plasma and see if it's still working, because yes, I never use it anymore. Boy, that sure would be nice if that's all it was. -cheers! |
Possibly a MOV. They look like disk capacitors but are basically a surge suppressor built into the gear. When a brief spike hits the power line they momentarily short-circuit. This sounds like it would blow the circuit breaker but it happens and releases so quickly that the inductance of the wiring absorbs it before the breaker can trip. On a heavy spike they can "punch through" with a bang and a slight odor of electrical arc or ozone. |
