Yes, pictures will help a lot, it sounds like they are ballast capacitors for the backlights lamps, they should be closed to the lamp connectors, one per lamps.

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 PRINCETON 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.

That is PC problem. Do you have correct video card driver installed?
Please download and install the correct drivers from you PC/Mother board maker.

It is just an audio cable with mini-stereo phone plug at each ends.
Radio Shack or PC repair shop should have them.

Does it do the same with other PC, if it does then you will have to open up the monitor.

Yes you need audio cable, stereo miniphone jacks at both ends (you can get it from Radio Shack) usually green color, plug one end into the green jack on the monitor, another end to the audio line out jack on the PC. Set the volume on the monitor half way up for now and adjsut the volume on your PC to the level you want.

That would be an issue with the VGA (if you used a VGA connection) connector issue. Or an issue with the graphics card. Try connecting another monitor, to isolate the issue.

possible hardware issue.

The set resolution is incompatible with the monitor. Use a monitor that works, change resolution then retry

first of all it may be a electronic problem so if you didn't understand what i am writing don't worry but you will not be able to solve the problem so you may have a problem with some capacitors in the line or you screen backlight is bad so to test these stuff you need a voltmeter and some knowlge with electronics

You do not need driver for monitor, but you do need driver for video card. You just have to make sure to set the resolution on your computer to the monitor native resolution.

You need to lower the resolution on the laptop before hooking up the external monitor.

I can give you the way to decipher the capacitor manufacturer codes, on the side of the capacitor.

This way you can find out what Voltage they are, and what Microfarad's.

set monitor to never turn off
OK

Try FN + F7

I have resolved this situation on other brands by holding down one of the advustment buttons while holding the power button in. You will see a message about "unlocking button" and a sliding bar if you find the right buttons.
