Viewsonic va1912wb-3 has solid green LED but a black screen


Hello,

This is a very common problem on this series on monitors. The problem is caused by filter capacitors in the power supply board that have failed. You can rebuild the board and the monitor will be as good as new. Here is a link to repair information for the VA1912wb monitors.

It can be the power supply DC caps for the backlight inverter circuits or the inverter circuits have failed, you will have to open it up.
If you are going to DIY and have proper tools and know safety precaution then please read on:
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed VIEWSONIC monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

You may need to load the monitor drivers.

I assume your PC sound is OK.

When you are plugging the green lead in the Moniotr / PC do you hear any noise from the monitor?? if not may be faulty.

Try plugging a friends set of speakers into the back of your PC.

ViewSonic VA912b monitor fading out during boot


It is probably the power supply, or the inverters.

Similar problem with solution, though it requires you to know something about electronics.
