Question about AOC LM 520 15" LCD Monitor
A 2004 relic tubby square
1024x768 reso only, it is not multi-sync at all. a real old dog
and the last one with the CCFL blacklamps on earth not dead, wow.
a treasure.
NO PC told at al
did not test this old dog on known good VGA PC that can do
1025x 768 and set that why first. (tricky blind for sure)
by blind I mean setting the PC up with monitor stuck on over-range is no picnic.
the great free service manual shows these words
Display "No connection Check Signal Cable" message. And go into standby mode after the message disappear
tests
does the monitor OSD screens work even with PC missing.
power on , under 15second , press menu, button
if menu is wreck(green?) the monitor is bad.
end story,
see page 3 step 3 hear and do the OSD reset..
shoe drops does green screen end if vga cable is fully disconnected from PC if yes then the GPU card is bad. in PC (unstated PC/card)
the GPU with dead R and B analog pins gives you green only screens.
that is it on 2004 mons.

Hook up that monitor to another laptop or computer. If it works then its an issue with the vga port on your laptop. If the monitor still shows those lines then you know for sure the monitor is bad and it will have to be replaced.

I have the same green screen -- but it went from green to black after I pushed a few buttons. Now it just stays black, but the power button stays blue as if everything were fine and connected. Also, all the monitor setting buttons still work, and are displayed on the screen, but the background just stays black. Any help out there?
