Having problems with your ViewSonic VX900 19" LCD Monitor ?

I noticed a post you made about the Viesonic VX900 and fuses

\015 I'm interested in saving $80+ shipping on a new inverter board and don't mind soddering which item in the image is actually those fuses and do you think radio shack sells them? http://www.lcdpart.com/images/DAC-12C024MSS.jpg\015\012\015\012can you email me at [email protected] I'm not on my computer and I've never used this site before LOL. found it while searching.\015

Answers :

I think you have bad CCFLs, (Cold cathode fluorescent lamps) they look like small flourescent lights and are used to light the screen. On smaller than 17" screens there are two, one on top and one on the bottom. 17" and larger monitors have 4 with real big ones having 6. If you attempt to change them be very careful not to crack the screen and remember the order of all the layers of the screen. The cost of the CCFLs along with the difficulty in doing this repair makes it not worth most peoples trouble....good luck
The fuses are on either side of the connector. They are semi transparent SMD chips. It's easy to see if they are flow or not, just look at them with a magnifier.

The problem with my monitor is everything works, I get a picture. But after turning the monitor on, the backlight almost immediately goes out, but you can still see the picture just barely.

Any advice on where the problem is? I'm guessing on the inverter board. No obviously blow parts. Capacitors maybe? There are to large electrolytic cap on the inverter one for each side.

Has anyone actually repaired one of these successfully? And what was the failed component?
