If your amp looks like it's going to work as normal (ie the front display lights up as it should etc), but then the amp goes into protection mode when the anti-thud circuit times out, then I know what's likely to be wrong.

It's one of the power amplifier channels which has gone faulty.

I just found this out after having this problem with my AVR-1906.

I took the amp apart and de-soldered the suspected channel power transistors (centre channel in my case).....and hey-presto! it fired up as normal (obviously the centre channel would be out of service).

I have ordered the replacement transistors from Farnell (UK) at a miserly cost of around £2-£3 each.

Just waiting for them to arrive.

An alternative is, if you don't use all your channels, take the transistors from a known working but not needed channel and swap them over with the duff ones.

Hope thats of use!

This is an indication of an internal problem. Typically this is shorted output transistors. Expect a parts cost in the $25-$40 range for this repair.

The power surge may have killed the power supply on the unit
If you have home insurance , see if your policy covers it
If not, it would be too costly to service ( Over $100)

Red power light blinking on my denon avr 1907, tried reset procedure, no speakers hooked up now and it still goes from green light to blinking red light and shuts off...Any clues?


This is a protection mode. The receiver protection circuit detects an internal problem like missing power supply voltage or blown channel and shuts down the receiver. You need to bring the unit to a repair facility.

I have h/k avr 85. Power makes a clicking sound when trying to turn on. It's a Orange light around the power button. When I push power it turns red. Please help me.


It is possible that the amplifier had encountered a fault with a higher current drain which had triggered it to a protection fault condition. The fault can be your output drivers- the MOSFETS/IC's fitted for both the channels, Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier. Sometimes this can be a noise like a HUM or HISS before the protect works. Faulty capacitors in these circuits also can cause similar issues and needs close observation.
You need to confirm and replace the specific stages or outputs. If not there can be issues in the mother board, maybe the protect circuit by itself is shutting off due to a faulty bias , maybe a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the protect is off then check for short on the speakers.

I have an Harmon Kardon AVR 85 and the power will not come on. The batteries are good in the remote, I have unplugged and plugged the unit back in, but the red light stays on and will not power up. How...


First of all, if you have just been powering up with the remote, try pushing the actual button on the unit. From owning a HK receiver, I found out that if the power switch is out, it will not turn on from the remote. Duh moment when I discovered this.
It also might be an internal fuse or circuit breaker that is shorted or tripped. If there is not an outside breaker or fuse, send this to a repair person. Sometimes there are capacitors in the power amp circuit that can hold a lot of voltage for a good length of time. You could get shocked. So, you might want to let the repairman handle this. Otherwise check for an outside breaker or fuse, and replace if needed.
You can also check Harmon Kardon's site for customer support.

Denon AVR-1100 receiver "PROTECT" mode


replace all the electrolytic capacitors in the power supply. i had the exact same problem with mine and once i replaced the capacitors it powered up and stayed on and worked perfect.
these capacitors tend to fail as they're of poor quality.
this fault is very common on denon receivers, especially the later models.

hope this helps?
