Having problems with your ViewSonic VA912 19" Flat Panel LCD Monitor ?

Screen flashes "on" and then goes black on start up...

\015 After working "normally", today my monitor went off/blank/black within one second of starting up... Turning the monitor on and off using the monitor switch produces the same result, i.e., on briefly and then off. The same happens when I use my computer to turn the monitor on/off.\015

Answers :

This is usually a bad capacitor problem. They would need to be replaced, or get a new monitor. Some shops will work on them, but you have to weigh the cost vs buying a new monitor for almost the same price.

\015\012There are some websites on repairing your own, but you need to know a bit about soldering and such.
About 2 years ago I bought 2 VA912 monitors. All was fine until about a month ago when one of them died leaving nothing but the flashing green LED. Last week the other one died in exactly the same way.

\015\012After seeing Palrepair's post I did some more digging today on the capacitor issue and came across this thread.

\015\012A guy named drummerman explains how he fixed his VX922 by replacing 6 capacitors. Another guy called Gumby_08 was kind enough to post some pics.

\015\012I dissasembled one of my monitors and It seems that the VX922 & VA912 both use a similar power supply board. Sure enough, the tops of the capacitors on my PSU board were bulging, so with noting to loose, I replaced the 6 caps with new ones of the same value:
\015\012
\015\0122 X 1000uF @ 10V
3 X 470uF @ 25V
1 X 470uF @ 10V
\015\012
\015\012I re-assembled the monitor and powered it up, It seems to be working fine now :-)
\015\012
\015\012So I replaced the caps in my other monitor and now both are fixed :-)

We have an Envision 9410e 19" LCD monitor which is about 4 years old. Recently it has started being very slow to start up, especially in the morning after the system is not in use all night. The screen stays black "too long," then it starts flashing, so that the user only sees the images for an instant, alternating with black. After a couple of minutes, the picture kicks in. Sometimes it will do this later during the day, after a break, but not always. / We tried switching the monitor with the o
