Re: AVR 7000 audio/video receiver
Harman kardon amplifire are known for that.specially AVR 7000
but sometimes this comes from poor wiring and using a wire that will not conduct better sound. Remember your wiring is very important.you may think your wiring is currect, better to double check. even if your connection is ok and the wire you are using are not better to produce quality sound you will not get sound from every speaker.

The display is powered almost directly from the transformer. Very few parts in between. It could be the display itself, which I guess is an expensive repair...
But I have just fixed my display for the second time by re-soldering a connection, and you may be just as lucky ;-) Both times the problem has been a bad connection in resistor R810 on the front PCB. Not easy to get to, but if you loosen the front a little bit you can find R809 and R810 on the left side of the front PCB.
Power goes from the mains transformer (6,8V AC) through a couple of connectors, and then through R809 and R810 before reaching the display itself (on pins 1 and 58). If you are careful you can measure the voltage at the display when the front of the receiver is tilted slightly forward.
The left channel output in the amplifier stage is going out - could be a cold solder connection due to overheating. Check the left channel output of the power transistors solder trace - you can compare them to the right channel stage because they're almost identical circuits.
second row down.. not sure if it left or right side.. but one is a blank.. so don't use it for anything.. My guess is if your looking from the front of the unit it is the one on the left.. my 5805 just lost sound.. sucks...
Connect all of your cables to your display and then connect another set of cables to your audio variable out from the television to the input you wish to get sound from on the receiver. Then make sure your tv is selected to the input you plugged the wii into, for example, Front video or Video 1 etc etc.
I ran into the same issue with an AVR 7000 after it had been shipped to me. I took the cover of and found that the left and right amplifiers have a separate power plug into them. when I plugged to "bad" side back in everything worked great.
Subject: Backup Memory on AVR/DPR/HK series receivers.
In the event of the complaint: “the receiver is losing its memory (any programmed system settings)
when the unit is turned off, or after the unit is unplugged (briefly*)”:
Check and replace:
Location: Front PCB
Description: 0.047 Farad 5.5v capacitor
Part number: # P10790-ND or # J3432147324X
I'm having the same problem and this is how far i got so far. I don't kwow how to get and replace this part.
