Denon AVR-3200 wont go into standby mode


Not sure what you mean by standby mode. The power button on most of the audio remotes I deal with merely turns the equipment on and off.

I'm unable to turn ON my harman kardon avr 300 rds which is always in standby mode


It probably needs a new servo switch. I would recommend taking it to a qualified technician for repair.

Avr 235 power at standby mode but sometime unable to power up, please help. A lot of thanks.


Open the unit and measure the voltage across the reset microswitch on the transformer board (with the unit in standby). It should be a hi signal, over 3 volts. If it is low, below 1 volt (when you can't turn it on) it is sending a constant reset signal to the cpu. Remove the switch and try again. If the problem goes away, the switch was bad. Its a service switch so you don't have to replace it.

The receiver turns on and immediately goes to standby


The unit is going into protect mode. Lets hope it has done the job and the receiver has protected itself from failure.
Protect mode can result from speaker wires touching each other or the Amps metal case. Check that first.
It can also be caused by unstable ohm loads if too many speakers are connected to any of the outputs especially zone 2.
If you can remove all speaker wires and turn the unit back on. If it stays on, turn the volume down on the main zone and zone 2 if connected. Then reconnect speaker wires.

Denon AVR 1603 goes to stand by mode


It has a blown channel, unless you are good at repairing them I suggest an authorized Denon service center. This Denon not only needs the shorted output transistors replaced, but a few resistors, a couple of driver transistors and a capacitor on the preamp board as well. alot of parts to be replaced. I have repaired about a hundred of these over the last few years and my shop charges about $200 for this repair, other shops should be about the same.

Stuck on standby


Unit is in protect mode there are a few problems that can trigger protect mode the most common is blown channel (shorted outputs). Sometimes one of the 15v regulators may go bad causing imbalance of supplys triggering protect mode. Also sometimes a bad solder connection could cause unit to go into protect also. I work for Denon authorzied repair center in Michigan if your nearby and Shipping to Michigan is economical let me know kstahl65@att.net

Going into protect due to either blown channel or probably a 15v regulator might be down which I have seen many times also. causing unit to go into protect.
