Problem: when I turn the monitor on I
can see a display for about 2 seconds. The display disappears. If I
turn the monitor off, then on, I can see the display for about two
seconds, then it disappears again. The cycle continues. The symptom
is the same with no signal input, and with input selected for VGA or
for DVI.
If I shine a flashlight into the screen
I can see a very faint display. I believe this indicates a backlight
issue. I could be wrong.
Can anyone help me find a
service/repair manual for this monitor?
Can anyone tell me what parts to look
at for the backlight power?
Can anyone tell me what the voltage
that drives the backlight might be?
Thank you all in advance, for your
assistance.

Bill, if monitor not covered by warranty, the check out YOUTUBE for long 8-12 minute video clips of LCD monitor disassembly or LCD monitor repair to find out what the major cause of your monitors SYMPTOM that you described above. Here is a small hint for you. If you didn't see the displayed data on the BLACK lcd panel with the flashlight "trick" then you would know that the entire "switch-mode-power-supply" was in complete SHUTDOWN mode or even blown the "line-in fuse" for the monitor. Also try a visit to www. ccl-la.com/badcaps.htm and view some of their vids on repair of lcd SMPS/INVERTER supplys and cold-cathode-fluorescent-lamp replacement. They also do the repairs and return shipping. Please rate this on fixya if this response was helpful. Bye for now. 12fixlouie
