Problem with Bryston 4B SST.


Just today I noticed that when I turn on my Bryston the red clipping lights come on for a couple of seconds and then turn green. This is something new. Can anyone provide any insight as to what this may be? I’ve searched for this but have not found this exact issue. Any help will be most appreciated. Thank you.

This one monoblock in question has always ran 10 degrees hotter than the other. Not until I moved my rack did it mess up completely though. I'm using another amp and it's not having a problem. 
The man who repairs out of warranty Bryston has a set of parts he will install no matter what the issue.  I sent a preamp in for a new power cord and got a note on my bill, "Standard (refurbish?) kit".  I might have forgotten the exact word following "Standard?.  So, $240 for a cord.
He must've replaced the caps and got it back to spec for 240, think they'd go that much for just a cord?

I sent both amps in to Bryston, one had a loose connection according to them. They Tightened it up and the other one has the slight vibration on the starting circuit and they said we can't do anything about that!  The note says it shutters! Cost me almost 400 for shipping. When I go to move up the line A prospective buyer will probably not buy the amps now. Thanks Bryston
