these machines dont have a Y2K problem! (as a matter of fact, according to
a DS5000/200, it is 1976 right now :)

this is good advice. i'd recomend cleaning it thoroughly as well (incl
perhaps removing the motherboard for cleaning). I had a 5000/240 that
would not function at all, until i cleaned it, and then like magic it
worked! (and has been working for a couple years now!) 
Whats your video arrangement? i've seen PMAG-B's fry on occasion from
poor grounding situations, whic caused quite notable havoc on the system,
naturally :-) just a thought. 

at least you know you've got power if the LED's are illuminated.. 

happy hacking,
