Have a look at the Sun Hardware Reference at:
ftp://ftp.picarefy.com/pub/Sun-Hardware-Ref/OLD/parts
Specifically look at part 3. (Search for "2050 CPU VME")
It has a list of the diagnostics and the led patterns which go with them.
It looks like bad memory.

If any one can decode the 'heartbeat' LEDs here is the code.
Looking down at the edge of the CPU board:
=============[Empty connector]=========[oxxx ooox]====================
where x is LED off and o is LED on.
I would like to mend this myself if possible. If it is going to require
component level diagnosis and repair then please bear in mind that I
haven't used a soldering iron or meter in anger since I was mending
televisions at school - when they all had 405 lines on the screen and
valves.
