Panasonic SA-HT640 acting weird

by oldadmark / November 18, 2012 2:03 AM PST

Our Panasonic Receiver, which also provides us with DVD, AM/FM, and AUX for Sound Surround has been acting weird. We've had it about 5 years now. While watching TV using the AUX function enabling the sound surround, the unit flips over to what sounds like DVD disc function without any input from us. Also there is this weird "Whirring" noise that is constant. If the receiver is bad are my 4 component speakers no longer usable?

Well the whirring sound might be

The fan. Any good tech can get in there to clean the unit and if you are very lucky the cleanup will help. Fans do not last forever so get a quote from the shops on how much to change that fan.

It IS the fan

My son came over here today, unscrewed the fan from the back of the receiver and confirmed that the fan is the problem. It was an easy removal with the fan having a short set of wires and a 3-prong (female) plug. If I can find the fan at a parts department somewhere I think we can install a new fan. Anyone know where I can buy one?

Here, let me open the water valve a little as you try to sip from the fire hose.
