When monitor is turned on the power light turns green but the screen is blank. i had it checked by a repairman -- whom i think repairs TV monitors really -- and he said the problem has something to do with the system and he can't do anything about it? It would be nice if this could be repaired because I really like this monitor because it has built in mic among other things, but if it will cost more than getting a new one then ...

Re: monitor is blank but green light is on
If you disconnect the data cable while the monitor is on, you should get a red and cyan message telling you to check the cable, that assures you that the problem does not coming from the monitor, instead check th video card.

Ive seen this on other monitors. Look for a 1 and 2. Some monitors do NOT auto detect a signal, and this one might not. Look for a way to set the monitor from Digital input to VGA input. Try that and see.
This looks like a problem with the video card or the power supply to the monitor. Try connecting a different monitor and if you still face the same problem then probably you may need to have a look at your video card or its connection in motherboard
Self-Test Feature Check (STFC)
Your monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. If your monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:
Turn off both your computer and the monitor.
Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove Analog (blue connector) cables from the back of computer.
Turn on the monitor.
The floating 'Dell - self-test Feature Check' dialog box should appear on-screen (against a black background) if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains green and the self-test pattern will scroll through the screen continually.
Turn off your monitor and reconnect the video cable; then turn on both your computer and the monitor.
If your monitor screen remains blank after you use the previous procedure, check your video controller and computer system; your monitor is functioning properly.
It appears that the display resolution set in your display properties is out of the range that the LCD can display.
Boot to the ENABLE VGA MODE by pressing F8 to get the Windows Boot Menu. If you can get to the desktop, then go to display properties, and see if you can change the resolution to higher settings and maintain video. (If the video blanks out, then it should revert to the previous setting in 15 seconds)
You have bad capacitors on the power board. If it was the inverter and the transistors associated with that then you would still get a solid green power light and shining a bright light into the screen would reveal an image.
Easy to repair if you have some electronics knowledge, if not, then your local TV repairman should be able to help you out.
Hope that helps =)
