Question about ViewSonic G810 21" CRT Monitor

1 Answer

Screen has 1 solid bright vertical line

Hi... I own a Viewsonic G810 CRT monitor and for the last few days I have been seeing frequent flickering on my screen when I use it. This morning before I left for the day, it was getting worse and when I returned home in the evening, I found my screen black with 1 bright solid vertical line running through. I turned the monitor off and now there is no image/vertical line. Have I blown the bulb? IF so, what are the costs associated and is it worth the repair? It's approximately 5 years old and it is being used quite often, as it's my main work/house computer. Thx

The brightness and contrats always appears on the screen.It increases and decreases frequently...

This problem is due to a defective microswitch in the brightness and contrast button of your monitor. To rectify this problem, you'll have to replace this microswitch. Please refer the servicing to a trained repair technician.

Hope this solves your problem. Thanks.

Screen flickers

The problem is that it is on the verge of going out my mother had a monitor go out and it did the same thing. Also if you have any high frequeny things around your monitor thatr also migh be the thing. Try a magnet or demagnitze the screen if you have one on it.

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

if you get a video camera & wave it from left to right while pointing it at the screen you'll just see the image in the flicker
