Default Marantz 7200: strange distortions

My Marantz 7200 I use for a home cinema theater (it has nice surround sound processor) started to distort as if something is heavily clipping in all channels. I opened it on the bench, looked inside, but did not find any bad solder or something similar. When I connected a signal generator and a dummy load it worked fine. I kicked all boards by a screwdriver, no result.
I put it back and it worked fine for a while, then started to distort again suddenly.
What is strange, internal FM radio sounds nice.
Any clue?
I have no schematics, unfortunately. It has lot of small PCBs soldered vertically and fastened to the rear panel, so it is very hard to troubleshoot...
The Devil is not so terrible as his math model is!
