Having problems with your ViewSonic VG2021m LCD Monitor ?

Connections are all good but it has flickering lines in the background, mid screen. I have checked it in several different connections, laptop and work PC. when left for a period the screen goes blank and it can only be reactivated by pulling out the power supply and reconnecting. I'd hate to think that it is on the way out - it is only 3 years old.

Hello,

The problem you are having is usually caused by a power supply going out. When the power supply starts failing it starts by not filtering the power like it should. This causes the controller board to act strange. If you look at my web site at: www.ccl-la.com/badcaps.htm We have pictures of the most likely cause of the power board problems. There are parts called capacitors that get damaged by the heat that get trapped in the monitor enclosure. After exposure to enough heat they pop the tops and cause power supplies to die. If you can handle a little soldering then you should be able to remove the back case and look over the power supply. Look for capacitors that look like the ones in the pictures on our site. You should be able to get replacement "caps" from Radio Shack or online and de-solder the bad caps and solder in the new ones. Re-assemble your monitor and you should be back running. If you have any questions about replacing the caps just email me.

Hello Grant190,

I'm afraid to say that indeed your having power problems. It does sound like a connection problem, but if you have already tried reconnecting ect then that rules out that problem.

From experience LCD's do not last more than a few year's before something goes wrong with them. Without actually being able to electronically test the inner components of your LCD the exact malfunction can not be determined.

Your two option's are basically having it repaired, they will diagnose the problem and let you know what it will cost to fix it. (You will likely need part of the power system replaced). It's likely this will be cheaper to have repaired then a new one would cost. That is something you will need to decide upon.

Post back if you have any further question's or comments. Id be happy to answer any question's you may have. Thank you for choosing Fixya!
