Any audio/home theatre experts know what would cause sudden static?
I have a pioneer receiver (which I got off moofi actually).
Hasn't missed a beat until this week. Last weekend the power went out, and I didn't really notice anything. Then last night my friend noticed a weird high-pitch static going on in the background of the show we were watching. It really wasn't that noticeable so I just ignored it. Today the power went out again for about 15 minutes (probably just fixing something leftover from last weeks storm) and now it is extremely bad and I can't really watch anything. The audio comes through fine, but there is this high-pitch static squeal in the background (which seems to react to the audio it is receiving, i.e. when the audio I am playing gets louder like when someone talks, so does this static noise in the background).
I tested multiple sources and formats, so I am pretty confident it is the receiver and not the media or cables.
Was this caused by the power outage? What can I even do?
