Hello,

I need some help determining where a LOUD POP noise is coming from.
While listening to some music last night I heard a LOUD POP coming
from one of my AV components. (To intermittent to trace) *The POP was
so loud that it startled me so I turned everything off only to hear it
again about 3:00am while sleeping. (Even while they were powered
off!!) *Does anyone have any idea what the heck is causing this?

PS: Everything appears to be still working...

Thanks,
V

Take all the components out of the rack and look at the power cords and
outlets, you should find some smoke tracks.
It sounds like a dried out power cord has an intermittent short.

Thanks
I found out that there is a known issue with the Direct TV HD21
receiver and the Sharp Auqos when connected with an HDMI cable.
