Hi,

I have a Denon DRA-935R receiver and unfortunately it has stopped working
recently[1]: when I plug it in and switch on the main power, it immediately
goes into standby and doesn't respond to the remote control. (There's a led
on the volume dial which does burn)

What I've done is a visual inspection of the interior of it, and all
apparently is ok - that is, I couldn't find any no exploded caps etc. or
blown fuses. Probing a bit with my multimeter showed the power supply to be
-at least- partially ok, that is, it supplies around 40V~ to the main amp
board - and since the LED on the volume dial also burns ok, I assume the
low-voltage part of the power-supply is working.

Finally, there's a relay which helps in providing power to my cd-player;
this clicks on and off rapidly when the receiver is powered on. (And,
subsequently, this power output is not provinding power -- which is
consistent with the device being in the standby state).

Can anyone help me investigate (and/or fix) the cause of this problem?

(if it helps, I've got a picture of the internals of this amp online at

Cheers,

    suddenly went into standby mode and it hasn't come back since.
