Hi There DEKCAT
Its very unusual for both channels to blow......
I suspect that there is a blown power fuse inside the case......
There are fuses sometime located on the outside rear of the case and these can be easily checked to determine if they are blown..If you find one is blown please replace with the corrrect rated fuse,..... its current rating wil be on a small label on the case outside rear. like 1.0amp, or 1.5amp etc...
If you need to go inside the case please ensure the power plug is removed from the wall socket first.
You will find small glass fuses in the DC power supply feeds and probably one of these has blown, once again replace with the correct rated fuse.
Im not sure if your amplifier is a FET type or a large 32-40 pin IC type as if these are blown you will need a service person to do the replacement...
Please note there is a small relay that clicks 20seconds after turn on at the switch....if this click is not happening then there is problems with the timer circuit or the relay itself...
This relay controls the output to the speakers and as such stops all the sound output if its not working...so the first thing is to check all fuses, if they are OK then check the Relay operations....
Cheers From YUBEUT

Speaker fuses are generally fast-blow styles 250 volt glass
If an amp shuts down, with speakers connected, it sounds like one of the power supply lines does NOT like what it's "seeing" . Probably output transistors bad ( or module)
Take it to a tech.

1-make a reset to your system.2-repeat your speaker setup.3-confirm that you assign your sysem for 5 chanell surround system.-4-change the cables between left and right front speakers if the trouble go to left channel you will have a problem in receiver itself-if the problem exict you will have a problem in speaker itself(cable or speaker)

Congrats, you yourself is a good troubleshooter. Just pinpointed your problem. What you just diagnoist can be easilly checked just by taking other good known speaker. If that works your speaker is short check for audio output wires. If not your card needs replacement. If need further clarifications just comment.
