Marantz SR9200 "Check POW5" error.

[David Farber]

This Marantz SR9200 will show a Check POW5 error on power up. The complaint
from the customer was that it was working, then stopped working, then
started working again, then finally it would not power up correctly. When I
first put it on the bench, it worked fine.But the next day when I powered it
up, the POW5 error came on in the display. I did some browsing and found out
this was a fairly common problem and the power supply had to be repaired.
However, I cannot find any fault in the power supply. Then I found this
thread about a loose white wire:
http://forum.ecoustics.com/bbs/messages/1/268085.html But that is for an
SR7500. And there was this thread:
http://www.avsforum.com/avs-vb/showthread.php?t=960488 which again was a for
a different model but did indicate that this problem was not out of the
ordinary.

Anybody know what the fix is for this?

Thanks for your reply.

Hi, Dave.

There is a service bulletin on this, although I have not seen the problem
personally. You need to hard wire the temperature-sensing thermistors.
Apparently they develop some sort of bad connection at the plugs where they
plug in the amp board. Real pain in the ass to get the amp ass'y out of one
of these.

I'll see if I can get a copy of the bulletin and send it to you direct.
