Sounds like wiring problems. Unhook everything, then get owners manual for proper instruction

Instead of replacing you can try and clean it. There are a lot of good contact cleaners out there.

I have an RX 600 - which has just gone 'phut' - which is how I came today to find this website ! I once had your speaker problem but eventually tracked it down to a bad connection of the speaker cable into the rear of the Receiver. Plastic sheathing and dust was partly in the way. Strip off a bit more plastic to expose fresh bright wire, and remake secure tug-proof connection before you try anything else. Oh, and while you doing it, do the others as well !

Try only A speakers.

I'd suspect that one of the two output transistors on that channel has gone bad. If you are unsure how to test or troubleshoot this, then you might try replace both the NPN and PNP outputs and catch the bad one that way. If your amp uses an output module then you would of course have to replace the module which would replace all the output transistors on both channels. Good luck. Another thing to look out for, is the emitter bias resistors. They are the large white ceramic ones near the outputs. Sometimes one of those will open up too. They will be of a very small resistance value like .5 ohms (point five ohms) or something in that general ballpark, and have a wattage value of typicaly 5 watts. So they are pretty big resistors. Be sure to check them all even if you do find a bad output transistor. They will often go out with the transistor. Good luck.

if you say you checked the wireing ,did you check the speaker. disconnect on of the other speakers and connect up the center to see if you get sound. still no sound speakers bad. Got sound try unpluging unit for a couple of hours then try it again. still no center . Time for the repair shop. Good Luck
