This is the same problem with my 4 VG800 Monitors, you should be able to find the correct capacitor on your monitors by following the same procedure, I'm sure the boards are similar. Just get the correct value capacitor and try it in parallel with the initial filter capacitors right after the DC power in.
Alright, I had 4 VG800 monitors with the exact same problem. The front
led is blinky OR constant reddish/orangish OR picture is white with
colored vertical lines OR no picture with whistling from the back of
the monitor and backlights illuminated. All problems have the same
solution. You need to disassemble the monitor (2 screws on the back,
remove lower front button panel, remove 2 screws holding panel in and
remove speakers, then remove panel and unplug speakers. Now remove
lots of tape and screws from the cover in the center of the monitor).
Now that you've exposed the amplifier board and the VGA to LVDS board,
you want to look for the pair of 25V 100microfarad capacitors that are
nearby the DC power in (they are right next to the black "100"
inductor). Desolder the capacitor farthest from the DC jack and
replace with an electrolytic with the same specifications. If you want
to check that this is the correct solution please put the new capacitor
(WATCH THE POLARITY) in parallel with the capacitor there want watch
the front panel indicator go green and the monitor work properly.
I'll be posting and Instructable entry in the next few days on the
process, watch for the username Waterppk on the website
