Hello there -Dont know your name,but mine shuts down too fast to tell.To answer
your question,the flouro tubes age & draw too much current causing shutdown @
convertor ps.
So,with that,maybe isolate tubes,scope the waveforms etc.Highest failures I see
are the tubes,bad sm electrolytics all over the place[main bd/convertor]
FYI Site bylaws dictate you have a sigfile.I didn't even know what that was
when I joined.Everyone is pretty helpful here.Regards,
Pete

Pete,
I have a similar problem with a DELL 17" LCD in for
service. Does this Compaq you're working on also show
OSD or self test mode?
I wonder if these units develop backlight problems
prematurely. My experience is that HP will not sell
service literature on their monitors.

Comes on then blinks right out.Scoped anodes of the Hi
V xfmr drivers and saw great swings but just hash. HP
doesn't address the Hi V ps on the parts site.Anyone
know where I can find one.Anyone worked on this guy?
