\015 When i first turn it on, it works fine. but after 2 0r 3 min, the whole screen goes dim, mostly on the left side, darker on the left side. the screen flickers a title for 3 min or so, untill it finaly goes black enttirely. used flash light and can not see anything on the screen after it goes black. power lights stay on and steady green. restart monitor and it does it again.\015

Answers :

This sounds like the inverter has gone bad. If the bulb were bad only, you would see a faint image on the screen with a flashlight.
\015\012The problem is on this monitor, it will probably cost about $100 or so to take it to a shop to get it fixed, and that is nearing the cost of a new monitor.
\015\012If you are a little bit handy, and can disassemble the monitor, you can replace the inverter. The hardest thing about this, is getting the monitor faceplate open. Just use something firm and softer, such as a nylon spudger (this is something you can find online) or you can carefully use a thin scredriver. You just have to be careful, those cases are really tight.
\015\012Here is a good guide for general ideas on how it is done.
