Hi,
I have a trouble with Marantz amplifier sr 5000: after a short period
of time it goes into protection mode, after some seconds it turns back
on, and after a while it turns back off and so on. I have tried
without any speaker or devices connected and it's the same. I took it
to Marantz official repair center, they said they have changed the
microprocessor. It was working fine for some months but now it's
happen the same. Sometime it works for some days and then again with
the same problem.
Can somebody help me here with a tip or advice? Thanks in advance.

Giulio

Sounds like a tough one all right. Could be the microprocessor wasn't the
actual problem after all. These things happen.
I'm not thrilled with the later model Marantz's. They didn't need to make
them so difficult to service. Even most of the Yamaha's are easier to work
on.

If you aren't a tech this is probably beyond you...
