Hi, Happened across this forum looking for some remote info. Had a similar problem with my 945...main speaker outputs started to click off & on, no rhyme or reason. Found that the solder joints on the speaker output relays were cold (poor soldering). Actually happend twice, two different relays. Took me a while to find it, reflowed the solder, that solved the problem, over two years ago now. Are you able to dig into the receiver? Do you have a (good) soldering iron and some solder? If not take it to elec. shop and tell them to look for cold joints on the relays.

First off, you want to correctly isolate what or which channels are/is bad. Use one good known speaker. Connect that speaker, one channel at a time, and test that channel with a fixed volume level (don't adjust the volume when you check each channel). Isolate the low level channels and make note of it. Note: each channel has their own amplifier. Once you've isolated the bad channels, take it to a repair shop and tell them the bad channels. They will then locate the circuit and narrow down the search to fine the problem - it's usually a bad solder connection. If it blows fuses - more likely a shorted transistor. In your case it's a bad solder connection.
