SA8 5.1 receiver overload comes on with no sound

For a time I only heard sound on the left if I powered up then dropped back to normal listening levels. Now the overload comes on with no sound whatsoever. I removed all the incoming wires to see if there was one shorting out but no change. Is it worth fixing?

Denton receiver shuts off when there is a loud sound from the show


Your Denon receiver may be going into overload, which comes from playing it too long, and too loud. Try reducing the volume to 1/2 your normal level. If you still have issues or questions, please visit my website at audioserviceclinic.com. Thank you.

Since this receiver is old-school stereo-only from the pre-subwoofer-era HOW are you driving the sub? Please refer to ITS manual and connect it properly. The speaker outputs for this box are for single speakers only.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

It's probably self-protecting from heat build-up.

Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.

Overloading


hi mate, ive had the same problem before with this amp. i bought it new aout 6 years ago and bought another new one about 1 year ago, new, for £70!

on the first amp there was a problem with the surround sound aspect, it kept overloading when turned up even a fraction, it would tick 4 times and power off. Eventually the surround sound stopped working all together and whenever selected made a VERY VERY loud hissing/crashing noise through all my speakers, blowing one of them, SO BE VERY CAREFULL.

when that happened i assumed was broken so bought another one, and had same overload trouble when i got a new speaker package.

Im pretty dam sure it was the ohmage ratings being different on 2 of the surround sound speakers that srewed the 1st one, so id suggest you check theyre all ok, as well as the speaker watt-age.

what are the specs on all your speakers (ohms and watts RMS)??

do you listen to LOUD music through the 5.1 option??

hope this helps, if all else fails buy a new one mate, theyre so cheap. go into panasonic shops and see if they have any left.
