Denon AVR-2700 Stuck in Standby

hi, for me it was one of the main npn transistor 2SD2560 or equivalent that was burned and also the two 0.22 ohms/ 2W resistor near that transistor

the main units of denon amplifiers are often almost the same you can get a 2105 or 2106 schematic easyly on the net.

hope this helps

Here's the manual:

Good luck.

Thanks, but unfortunately while it says service manual, it's only the user manual.

This was for symptoms similar to mine?

Thanks!

If you'd like to email me at

notice the underscore "_" and reverse the domain to read "sbcglobal.net" I can e-mail you the manual in .RAR chunks for reassembly on your end. Please specify the size of attachments you can take, 8 meg or whatever.

Does it go back to standby and blink the power LED or not even respond to pressing the power standby button?

There could be a "secret decoder ring" reset procedure to unlock it after a protect mode has been triggered. This is increasingly common.

I downloaded the manuals - there is a reset (initalization) procedure.

Press and hold the STEREO and DIRECT buttons while pressing the main power switch. When the display segments all light up and flash at 1 second intervals you can release the buttons. These types of mysterious lockups used to be extremely common on some Denon models. Actually, it's still fairly common...

I will email you.

Only the main power (hard) switch has an effect - to turn on the Standby and Lock LEDs.

There is no response to any other buttons.

The power transformer never gets voltage, even for an instant.

We have tried the STEREO and DIRECT buttons at the same time while turning on power - no effect.

Thanks!

hi, yes the symptoms where completely similar (almost)

I bought a 2105 denon on second hand it worked but I found the central voice not working I opened it , and found components not soldered on the central voice !!!! so I resoldered them, and I got the red led and power down... after desoldering, examining, I found the transistor and 2 resistor bad replaced them, and everything ok now.

afterwards, I found the schematics of some denon amplifiers on the net and found all the main units very similar in all the schematics and also found a lot of same broken units for sale on ebay ...

hope this helps

Interesting.... Mark Z found the service manual so that at least should help.

I should note though that this unit never attempts to power up at all - only the Standby and Lock LEDs come on. There is never any voltage to the power transformer, not even for an instant. No clicking relay, no response from the remote. No response to the reset (STEREO and DIRECT pressed while turning on power).

Thanks!
