VA902b Viewsonic monitor just went black this morning while working. Tried updating driver. Reboot. Does display during startup and goes black again. Monitor problem or hardware? I have 2 monitors.


The best thing to do to isolate the problem is to connect the problem monitor into a known working CPU. If the same problem occur, then the problem is the monitor. You may need to check if the power light (LED) is blinking or no light at all.

If there's no light, you may start replacing the power cable if the cable is detachable. But if it's built-in to the monitor, then send it to the authorized repair shop. They need to check if the panel is shot.

Thank you and good luck!

Viewsonic VG2021m Image Vanishes on Start Up


Hello,

It is the picture picture board on your monitor that is malfunctioning, since the power led or button is on, but the display screen goes blank after a few seconds, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity or any service center to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

Blinking Light

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
