How do I get the lights to work on the FM channel that runs the length of the receiver? Other lights seem to work but not the main one. Powers up and works fine....minus the lights. Thanks for any assistance.

There is no fuses for the speakers. Check setup. If the receiver has 7.1 channel input try to connect a source there so you can check output (amp) section and the speakers.
There is a 1 Farad "super capacitor" that needs to be replaced. You need soldering skills to do it. The board is accessible if you remove the front panel of the receiver. The part # is DB-5R5D105; you can get them on eBay for about $2.00 each. Regarding the center channel issue, you may have a bad solder joint on the P781 connector on the P774 board. This is the board that houses the output transistors for the 3-channel main amp board (P704). If not these solder joints, you have a weak driver transistor on P704, and troubleshooting would probably be best left to a pro. Good luck!
It is likely that something overheating is causing the problem, but nothing should be overheating. Cleaning won't hurt and may help but it is likely to require repair of the faulty component, perhaps a failing capacitor or amplifier.
please invert your cable and watch if the problem moved the problem in your cable change it with new one.from any radio shack near you or any electronic store.
I've just been told by my AV person that is a known flaw in the SR5002 that the power supply runs hot, blows out, and sometimes takes out other components by cooking them. Thanks Marantz. How about a recall?
