Question about Denon AVR-785 Receiver

Open Question

My AVR will not turn on after a power surge; unresponsive.

My AVR will not turn on and is unresponsive. I first noticed this after a power surge. Could this be a simple internal fuse that needs to be replaced, or what is the culprit?

SOURCE: denon avr-1404

Hello,
I got the same problem and on my AVR1404 it is the regulator
-15v (7915). You can control voltage on
R145 : +15v and
R146 : -15v.
The other side of these two resistances are joined together.
Good repair....

SOURCE: Denon AVR-687 cannot power on, no power light lit around power

Check the main power switch next to the large power button. It is a small push button. If it is pressed in and you still have no light around the power button then very likely you have a dead power supply.

Thus AVR part of the computer?


AVR = Automatic Voltage Regulation

It is not part of the computer. You buy it separately.

It protects your computer from power surges,
thereby increasing the durability of that equipment overall.

My unit is in stand by but will not power on


Disconnect the main power to the receiver and let it set for 15 minutes or so, this will allow the capacitors to discharge fully. If the receiver did not suffer transformer damage, it should turn back on. If you don't have a good surge protection unit with line conditioning like Panamax or Furman, get one! It will save you $$$ in the long run. Hope this helps.

You could be correct on the transformer. I'm kinda leaning towards a bad cell in the battery. Sounds like it will need replacing.

I lost sound from my Denon AVR 682 last night. Display and video are coming fine, but no sound on any input source setting. I have also noticed that a loud click noise that used to come after turning it on...


Reseat all audio connectors sometimes they get dirty. Do you have surge protection? Do any other audio functions work? Clean your remote change the batteries the mute may be stuck. I vote for the battries being weak and the remote will not clearly send all signals.

DENON AVR 2308 no longer works only after 3 weeks of purchase!!!


You need to get more details. What component has failed that makes them believe that a surge caused the problem. There is usually a thermal fuse inside of the main power transformer that CAN be effected by power surges. WIthout more details, I really can't rpovide any ammunition for your claim. Please request exact details from the servicer.

Thanks,
Dan
