[SunHELP] sparc 10 crash - help needed

[Arthur Wouk]

my sparc 10 crashed today. the main symptom is a lack of symptoms.

i removed the keyboard and monitor, attached them to another sparcsattion
and it boots just fine.

if i tip to the dead sparc 10, i connect but get no response when i
power reset.

when i reattach the monitor and keyboard, and power on with stop-d
keys held down, the leds on the keyboard go on and off two times, then
everything halts with only the caps lock key illuminated. thus the
POST does not run. the monitor's signal light keeps flashing - it is a
GM 20D10. there is no signal to the monitor apparently.

is this a power supply failure, a boot prom failure or an nvram
failure? any clues as to how to test?
