Question about ViewSonic VA902b 19" Monitor

ViewSonic Monitor Flickers

I got a ViewSonic VA902b Monitor and I'm connecting it to my MacBook Pro. When I turn the monitor on it will turn on and I can see the wallpaper, but it immediately in 1 sec being on turns off. Could it be some sort of fuse?

    Same problem.. I ended up buying another which works fine, so it definitely is the monitor. It will flash on for a second or so and blank. I know that system is booting and goes to windows vista. Would love to fix the old monitor.

    Exact same problem here... Comes on for 1/2 second and then goes blank. Turning the monitor off and back on repeatly gets me that 1/2 second look over and over, but it's not real efficient in getting my work done.

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!

I have a viewsonic va902b screen when I turn it on the picture flashes and wont stay on the screen, how do I fix it?


More likely to have bad caps in the power supply, that is the first place to check for bad caps with bulging top, it can also be bad inverter circuits, or bad lamps, open it up and post back what you see so we can guide you further, see example of failed VIEWSONIC monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

Hi.

To start test the problem on a different main outlet, if the socket or the network in the house is not well earthed you may get this problem.


The problem is given by an internal faulty component, probably a faulty capacitor.

When you unplug and plug back, the electrostatic charges in internal circuit will get drained, and this will compensate the fault.

The monitor must be tested at component level to find the fault.
