Question about ViewSonic VX910 19" LCD Monitor
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 www.instructables.com

Don't know if I'm allowed to advertise here but I ended up sending mine to Monitor Depot in Houston Texas, $110 including shipping and its back working...Wish I could have fixed it myself but there is nothing out there to help...Still a good monitor so I decided it was worth it.

Having the same exact problem...it started with the green led power light flickering and it would take a long time to come up and then it got progressively worse...now the led light flickers red, yellow, green and the screen displays white lines randomly as the led light flickers...seriously doubt that the monitor is repairable....paid $500+ bucks for this sucker and have only had it for 1.5 years...have 3 CRT monitors that only cost $100 bucks from the mid 90's that are all still running strong (none are ViewSonic monitors), so needless to say we are very very disappointed in the QUALITY of ViewSonic Products. Our Company Will Avoid ViewSonic Porducts at all Costs in the Future!

Viewsonic/Proview monitors are all notorious for this! I have to go into various sites to troubleshoot these monitors. These monitors have two major components that allow you to visibly see what is being display! These two parts are critical the Inverter & Backlight. I have found that whe the flickering begins, distorted lines, grey screen, multi-colors, lines in meshed in the LCD, blinking power light, solid blue screen, solid green screen. These are all major causes of bad inverter, or blown backlight! Now if this monitor has a power supply that connects directly into the serial connector that connects to the PC, then it could definetly be the power supply. Power supply is important as well because sometimes they do not put out enough power to display the image so if these monitors all have a power brick connected to a power cord. Then the power brick is the problem! I see this all of the time with these monitors! Let me know!
