Re: What may cause LCD monitor show image for a moment and then go standby

Hi Friends!

A friend of mine got an LCD monitor (dell p2211h) for "experiments". It
is not working - in the following manner: when connected to VGA and
power, it briefly show image (e.g. loading screen) - for about 1/3 of a
second - and then goes black, with power led turning blue from orange
(which seemingly means standby mode).

If powered up without video signal it similarly blinks rectangle with
the word "dell" for the same brief moment and goes black.

I suggested there could be some issue in the power circuit (perhaps, of
backlight?) and suggested she can use screwdriver to carefully open the
case and visually check for any blackened / sparking component.

I think this is probably all she could do not being guru of electronics
and repairs. However I wonder, if someone better acquainted with LCD
monitors may hint whether such misbehavior is a kind of some typical
issue and indicates some well-known problem.

Thanks in advance!
