[Sunhelp] Guru needed! Sparc20 died after move.

[Wolfgang Engelien]

Hello gurus,

the subject says everything. A sparc20 died on me after
moving it from one room to an other. There is no output
through the monitor anymore. The attached message was
gained through a tip connection on the serial port.
I tried to clean the machine, take the CPUs out, put
them in again, checked on the memory to be snugged in
correctly, checked all cables to be attached correctly,
checked the fans, hard drive and cdrom cabling ...
I had a partial success as one time the machine at
least tried to boot (with video output), but broke
afterwards with a watchdog reset (Both from cdrom and
from hard drive). Once powered off again the video
output never came back again.  

What can I do to reanimate the machine to work again?
Attached the console messages and the printenv output.

Thanks for all hints,
Wolfgang
