Question about Denon Audio Players & Recorders

Open Question

Denon POA 2800 Amp

The amp heats up considerably on one stage, too hot to touch; and then shuts down (protection I assume). It appears it will need professional repair.

SOURCE: Denon AVC-A1SE in protection mode

Hi,

After thorough cleaning of the speaker leads, PC Boards etc, I desoldered all the leads of the main two power transistors of the Left channel that had given problem earlier. Switched on the amp and bingo, it did not go in protection mode which confirmed that the two power transitors were the culprit. After checking the voltages and values of some other vital componenets vis-a-vis remaining left channels, it was confirmed that the circuitry was okay. The power transistors were checked again and found to be okay as well. I then took a chance and resoldered not only these two Left channel power trnasitors but also resoldered all the leads of all the other power transistors as well.

The amp was switched on again and this time also it did not go into protection mode. The amp is working fine. Problem could be either dry solder or short of power transistor leads by stray solder waste strand. There was no need to change any part which was great.

Thanks for help anyway.

AVR 2800 powers up and shuts off and lite blinks


Generally speaking this means a fault in the power output stage of the amp, which is the part in the pcb where the Output Transistors and the Aluminum Heatsink are, hope this helps.

When i tun on my DENON avc-2800 amplifier it comes up with 'protection'. How do i fix this


Please see the link below for an explanation of Protect mode. Specific to your model, the output transistors are likely to be shorted. This particular model will shutdown the entire unit if any of the channels have a problem. Without actually seeing the unit and taking some internal measurements, I cannot state for sure the parts required for repair. I would expect a parts cost in the $20-$40 range minimum.

THe word Protection is coming across the screen instead of input or other


Dissconnect the speaker wires. If you still get the protect message you have a bad output stage in one of the amp channels. If the message does not appear you have a shorted speaker wire or a bad speaker. If the amp is bad you could still have a bad speaker or shorted wire that could have caused the amp to fail. Resolve this before reconnecting to the repaired amp or failure will reoccure.

My denon avr-1906 amp will not turn on correctly. When the standby button is pressed the indication surrounding the button flashes green but when you hear the relay click in for presumably the power amp,...


The amp is shutting down to prevent further damage. This is what is sometimes referred to as protect mode. There is a problem with the final stage of the amplifier. The most common parts that fail are the output transistors. Figure on $15-$40 in parts plus the local labor rate for the total repair cost.

My denon avr-a10se stop working. When I start, aftr thr quick intiation the amp shuts itself and the red power light start to blinvk quickly - please help


This unit is in protect mode. This means that a problem was detected in the last stage of the amplifier section and the unit shuts down to prevent further damage. The most common failure parts are the output transistors. These usually run between $5-$15 each. Add in the local labor rate for the total repair cost.

I have the denon avr3600, the protection is on, how can i turn it off, thanks


Unfortunately you can not just turn it off. Protection means that a problem was detected in the final output stage and that stage was shut down to prevent further damage to either the amp or the speakers. The typical problem is either the output transistors on one channel or the output amp chip for one of the surround channels. Expect a parts cost of about $25-$40 plus hte local labor rate for repair.

Power Button Flashing Red


Check to make sure the +/- speaker output wires aren't touching. I've had this problem before with frayed speaker wire strands poking out & intermittently shorting to the other polarity speaker output. This amazing receiver actually continued to play at low volume levels, but if I turned it up it would shut down similar to how you are reporting. I cleaned up the frayed wires & this fixed thr problem. Good luck

Receiver shut down only when using phono preamp


You may want to try putting an attenuater in the line with the RCA's to cut the input signal back just a little bit. So you are not driving the amp so hard with your preamp.
