The AVR automatic voltage regulator normally gets damaged by a short in the rotor, wiring etc. MOST common is shutting the generator down under load and NO NO. The AVR goes wide open to try and maintain voltage on a gen that is stopping, always disconnect loads then shut off
If I understand your problem, you replace the AVR only to have it go bad after only ! hour. This is a very strong indication that the winding of the rotating field has a short circuit . If you do nor have meters and equipment to test, try this trick. In the wiring from the regulator to the slipring brushes, cut the wire and splice in a automotive fuse holder with a 3 amp fuse. If you run the unit and it blows the fuse, you then know the problem. Hope this helps you, Robert
I've had an AVR 3200 for about 10 years - occasionally (maybe once every 6 months), the error overload button comes on... for no real reason than i can detect (ghosts in the machine, maybe)... rebooting has always fixed it for me.
If your set up is HDR-AVR and TV all you need to do is go HDMI out from HDR to HDMI in(Sat.) of AVR and monitor out HDMI (or composite video) to TV. and select the Sat. input on the AVR. The sound is only comming from the HDR in this case and the composite video or HD video is being switched out to the TV when you select Sat. on your AVR
Denon has released a Technical Service Bulitin about this problem. To fix it, an authorized service center will solder a jumper wire to bypass a connector, which has been shown to fail. It has nothing to do with the settings, or setup of this unit as described in Solution #1. It has to do with faulty parts within the unit. Just call Denon for an authorized service center and it is a quick fix. I have a AVR-488 that had the same problem and was fixed with the help of this bulliten and fix. No problems since.
Eltax AVR-200 will start up in protection mode if the amplifer went into protection mode due to high volume before it was turned OFF and it will start at the same volume level as it had before power OFF.
To correct this you must shift to another input without signal, then turn the volume down before it goes into protection mode again.
It must be a contact problem arount the power switch, power cable, fuse or the condensator area. Maybe you can se a black color on the board. And checking the solderind points with a magnifyer can help too.
