Home Theater audio cuts out sometimes - overheating?

post #1 of 6
Thread Starter 
I have an RTD325W from RCA that I use for my home theater. It's connected to my cable box directly with an optical cable, and to the gaming consoles with the RCA-type red/white cables. Every once in a while, the audio will cut out. It only does this on the optical or aux inputs--never when watching DVDs. I don't put the volume too high, so it's not that. I've been thinking that maybe the stereo is overheating since it's on top of my cable box, which puts out quite a bit of heat when it's on, so I raised up the stereo using some empty jewel cases. Still had some cutting out last night. When I called RCA, their absolutely terrible customer service said it had to be a bad connection, even though it's done this with two different optical cables and a number of different sources. I asked them if I could send it in for a replacement and they said that they would have to hold onto the unit for a month or two before they could repair it or replace it, which is unacceptable. I'm very disappointed in RCA over this, and was hoping somebody had an idea of what I can do to fix it.

Possibilty that the speaker connection sockets could be shorting slightly,if its those push the tab in ones,then you insert the wire.Sometimes the wire can fray and a little strand of wire sits accross the two metal tabs inside,you can either try to blow it out with compressed air or take the top off and you a paintbrush to get in the gaps and dust it out.Also just to be sure check the cables and speaker wires for any touching each other.

It does seem like an issue with the receiver. Is it still under warranty?

If you really don't want to send it in, try doing some cable management. Make sure there is no interference between the cables. Try re-organizing the consoles. What I do on my home theater systems is use plastic soda bottle caps to attach to the 4 feet at the bottom, which gives a little more room for ventilation.

Other than that, I would just try to narrow down when the cut out happens exactly. For example, the audio cuts out when x type of audio is playing from y console using z type of cable, etc.

I know this seems really odd, but my surround sound cuts out when its too cold in the house. If I leave the front door open to get some cool air while benchmarking the computer, and my wife is watching TV at the same time it will eventually shut off and I will need to stop what I am doing, close the door & turn the heat on until it starts working. Not sure how much it applies, but figured I would put it out there

Well, I've moved the TV and peripherals to a different side of the room since I originally got it, which involved disconnecting and reconnecting all of the speakers. The problem existed before the move, and still exists. I'll give the push-connectors a look, though, to see if it could possibly be a short in there.

I got a 200MM fan for a puter and set it on top of my AVR reciever and since no problems. I got the idea from Frys that sold a cooling pad for a reciever,it's just like what cooling pad for a laptop.
