Re: LCD Monitor Problem - Turns on and off

It don`t sound like a bad inverter if it is running good when plugged
directly to the wall outlet. If it only does this when plugged into
the powersupply of the computer then this would be a problem of the
computers powersupply. Did you try to plug it into another computer
to see if you still have the same problem ? I would suggest to try
this first and see what happens.

Apologies if it's duplicated. Probably a Comcast problem.

I have a very unusual problem with an LCD monitor. I will try and
be
descriptive as possible without being confusing.

When the adapter for the monitor is plugged directly into a wall
outlet, and there is always current to the wall outlet, I can turn
the
monitor on and off normally. There are no problems.

When the adapter for the monitor is connected to my UPS and the UPS
is
turned off and then back on, or when the adapter is plugged into a
wall outlet and then unplugged from the wall outlet and plugged
back
in, I begin to have problems.

Specifically, in the two situations above, when booting the
computer,
the monitor will "buzz" briefly, the picture will come on,
and then go
off. It will do this several times during the boot sequence. It
will
do it once at the bios, once at the Windows splash and then again
at
the login screen. Upon each of the three occurrences mentioned,
the
monitor will "buzz", the picture will come on briefly and
then go off.

However?if I reboot the system several times, or when I'm at the
last
login screen, turn the monitor on and off several times with its
switch, it will eventually stay on.

I have tested this monitor with different video cards and on
different
systems, so it's not the video card or one specific box.

From the way the LCD is reacting, the problem seems to be similar to
a
bad ballast in a fluorescent light, is this possible?

Any suggestions (except leave it plugged in all the time? Is there
any
way to test this LCD with minimum equipment and knowledge?

Thanks in advance.

When the screen goes "off" does it really goes off? It
sounds like a
bad inverter or a bad ccfl.
