I've had a gorgeous Onkyo TX-6500 II sitting on my shelf for 15 months and am finally going to get it to work - or else. The problem is one or both channels don't power the speakers at startup. Sometimes the left channel is on immediately and sometimes not. The right channel never comes on at startup. Many times, after several minutes (5-8), the right channel does kick in, but other times, I need to run the volume way up or the balance control back and forth before I get the right channel. After the channels are both on, there are no problems with the channels ever dropping out.
I've used Deoxit, followed by ProGold on all pots, more than once, except for the volume control, which looks like a sealed unit. Faderlube used on the pushbutton controls. This hasn't produced any special improvement.
Tapping on the outside of what I assume is the speaker relay will once in a while bring the right channel up, but not consistently. Today, I touched the preout /main in jacks and static electricity caused the right channel to come on.
I've included photos of 2 components. The clear plastic box is seen from the bottom, while the black box is visible with the top off.
Any advice from anyone familiar with the Onkyo, or this type of symptom, will be greatly appreciated. I've got limited electrical skill, especially at the circuit boards.
My only guess is that this might be a relay problem, so I tried to see if I could get the clear plastic cover off. It seems like it will come off, but I haven't been able to see the trick. Further, don't know exactly what I would do if I did get the cover off, beyond using compressed air. Deoxit?
Finally, if anyone has changed out the function indicator lamps, any tips on actually pulling out a lamp and soldering in a new one, would also be very helpful to me. Working thru the front, I've gotten the lamp panel loose and see the lamps and wires. It looks very tricky to try to replace one this way however.
Many thanks in advance.
