There is most likely an overheated or burned out capacitor in the unit which is common now days. You can test ith an ohmmeter or a capacitor tester to see if there is one that is not in the 25-30 ohm range. Or 5 volts.

How to take protect off a denon receaver


Hello. DC Protection is not something you can turn off. It is a protection system engaged by one of the microprocessors (computers) within your receiver. If any of the amplifiers are bad, and producing DC voltage at the output, the micro will immediately turn the unit off, to lesson further damage to the amplifier or speaker system. There can be other causes of why the unit's DC Protection relay is not engaging, but 90% of the issues, are related to amplifier damage.

Dish HD-DVR connected to a Denon 3808ci via an HDMI cable. Problem is periodically, the screen goes black for a split second and then comes back. Rewind and play again the blackout doesn't repeat. When...


Your'e losing digital data from Dish or the DVR. Since even live TV is through the DVR it is always a potential problem when anything glitches. That it doesn't repeat on immediate rewind/playback says the data made it to the hard drive ok.

The Denon is only defaulting back to an analog audio feed upon loss of the digital (preferred) one.

If it affects the video AND audio simultaneously the cause is something common to them.

I'd look at HDMI cabling into the Denon from the DVR.

Don't blame the Denon just yet.

My $.02:

I'd skip the video right past the Denon to the TV/Monitor even if it means using component cables instead of HDMI, but keep digital audio coming in from the DVR. Added cabling and connections never improve anything. Plus, HDMI cables are expensive.

It would be interesting to see if the problem comes back and affects only the audio or the video.

If you use optical cable make sure it has smooth flowing curves and no small-radius bends that would lose light power.

I just purchased a used Denon AVR-3200 and have nothing hooked up yet but plugged it in on my kitchen counter and upon turning the unit on, noticed the error overload button was lit up but the unit did not...


Hi

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.

Unit turns on and immediately turns off.


YOUR SPEAKER IMPEDANDE MAY BE INCORRECT FOR THE SPEAKERS E.G 3OHM
YOUR DENON USUALLY USES 6 OR 8 OHM SPEAKERS SO IT MAY SWITCH OFF TO PROTECT ITSELF

My denon avr-1706 is going into protection mode immediately after turning on. whats the problem?


You either have an overloaded output or a shorted powersupply. If you have verified that your connections are not the cause then the problem is internal and will require service from a trained technician. Switching power supplies are notorious for going bad. Two of the main components are the FETs used for switching and the PWM generator.

Power button (light) blinks


Check your speaker cables, make sure none have shorted out. if they have, then thats why the unit won't power up. The units protector circuit is being activated upon startup.
