AOC monitor

[Bart Bervoets]

Picked up off ebay, had a burned 5V regulator, i fixed that and now i see
the picture but very dim.
Failed bulb or inverter or is there more going on?
Any tips?

Try posting on alt.rec.psychic they may have a clairvoyant who can tell what
model!

Another loser reply, you know just as much as i that there are general
problems with lcd monitors.
I'm not asking for model related information.
aol user?

Well I didn't see anywhere you said it was an lcd. I just assumed that it
was a CRT as I'm sure that Ian Fields did...

Now we know that it is a TFT monitor that helps alot since before I was
going to say it was probably a weak picture tube.

Usually a dim picture is because of aging backlights. This isn't always the
case though. You should disassemble the TFT screen and see if the ccfl lamps
are good and bright or if they are dim. I personally have an old viewsonic
vp140 LCD monitor with a dim picture, but it is not from the backlights
(replaced them). Oddly enough the screen appears to be aged or damaged
somehow to make it very dark. Possibly exposure to sunlight???

The pic isn't just dim, i mistook the startup from the lcd as a dim picture,
but i think either the inverter gets no power or is bad.
I found and replaced a 5v regulator on the pcb but before that the monitor
was dead, now a fain no signal warning can be seen.
Any way to find out which wires supply power to the inverter, as well the
output has 4 sets of wires, are there 4 backlight
ccf's?
If i can't repair this one i will salvage him to make a homebrew beamer,
done it before with an old tft screen.

*cough* Well what model is it? That could be useful in telling you what the
pinout for the inverte is, or better yet what model inverter is it?
