Hi there. It's probably your backlight inverter that has gone bad. What model is it ? The inverter can be on a seperate board, or on the main board on that viewsonic LCD. Is it a VX922 ? Common problem on these..

The Screen comes on for 1 second then goes black but you can still faintly see the image on the screen


It can be as simple as bad DC filter caps (leaking/bulging tops), that will be the first thing to look for, it can be more serious problem in the inverter circuits or bad CCFL assemblies.

VX900 19 in. Flat Panel LCD Monitor: when i turn it on the screen is black....


You may have backlight inverter failure, check the fuse as shown in my pictures, you can also have bad backlight assemblies also, but check the fuse on the inverter bd first, verify that you do have 12v at the fuse.

Monitor flashes on then off power light stays on whats wrong?? shows screen for about 3 seconds then goes black


Some 22" Viewsonics will have worn out bulging capacitors in the power supply that causes this symptom.

The monitor only turns on for a second and then goes black again. the green light stays on. what can be done?


More likely to be failed components.
Most common failure in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, falied 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 goes wrong: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further.

Blank screen


You probably got yourself a bad backlight or better yet a bad inverter board inside. A lot of experts found if you open this thing up and See any puffed up capacitors replace them as that could also cause this issue. But viewsonics had a issue with a bad capacitor on the power supply board.

I sure hope this information is Very Helpful to you!
