A couple of weeks ago the monitor (HP 2509m) on my computer (HP p6367c) died on me. The monitor had a flickering problem for a year or so (the flickering would last anywhere from a few minutes to over an hour before it stopped), then it would only display (accompanied by a hissing/static type of noise) for a few seconds before going black (the monitor did not turn off though).
Afterwards, I used the monitor (same model as the one mentioned above) from my Mom's computer. Less then 24 hours later it too had died (it suddenly turned off without warning and won't turn back on).
I tried plugging the monitors into different outlets with no success. Both had been plugged into a IBM Office Professional OP 500 backup power supply.
I'm currently using an old CRT monitor on the computer (no problems as of yet).
Is it just a coincidence that both monitors died within a short period of time or is it possible that something else (like a faulty video card or electrical issue) caused the monitors to die?
