Default sr5001 marantz blinking led

HI Guys,

I have to repair a Marantz sr5001. When i power on the amp the red standby led is blinking and nothing happens.

Everything looks fine and all end stages where fine.

Are there people who knows this problem, or is there any reset option.


regards Rick...

Default Clearly something is wrong

You should get the service manual for the device. It will help!
Check the microcontroller and protection circuits.
Remove the speakers and manually check all voltages.
good luck
