I have a Marantz SR-5000. It has been turning off and on by itself. If I have it plugged in and am listening to music it is common that it will turn off after a while. When it does this it won't turn back on immediately, but after a while I can turn it on and all of the presets have been wiped from memory. Alternately I can have the receiver in stand-by mode and be gone for several hours and often I will come back and it will be on. Once again with the presets wiped and, luckily, volume set to 0. Any advice would be lovely. I'm not afraid to dive into replacing PCB components, but unfortunately I don't know where to start looking to see what's wrong.

you mite not have to reset it, try checking ur fuses, it could of triped the cicrut when the power went out, normaly thats what happens unless it was a direct contact then, u mite wanna go get a nother receiver, and what i mean by direct contact, i mean like directly pluged into the wall
hope that helps

It is likely that the PA stage has developed an offset voltage in the output stage. The faulty amplifier channel can be found by progressively disconnecting the collectors of the of the power transistors until the protection fault disappears. Once the faulty channel is found the the cause of the offset has to be traced to the faulty transistor or resistor. Don't forget that if you can smell smoke or burning then there are likely to be components(esp transistors) that have been damaged by the fault.
I had a Luxman unit that destroyed 5 transistors in the output stage that was due to an open .5W resistor in the driver stage.
Good luck.

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!

I have this problem. it is caused by an o/c mains transformer primary winding. the clicking and flashing light is the stanbyy circuit trying to switch the power on to the main (large) transformer when it gets no voltage out it switches back off

For resetting sr6001: When power lights blinking, press "clear" + "pure direct" + "7.1 ch input" simultaneously for 3 seconds.
