The monitor on my laptop is very very dark. I can connect a remote monitor and use the unit that way just fine. If I turn the LCD screen towards a light source while using the laptop as a PC, I can see ghost images of programs that I may be using or the icons on my desktop. This tends to make me believe that the LCD monitor is not bad and that it is some other issue. Can anyone advise please.

Re: Dark LCD Monitor
From what I understand there may be a problem with the power circuitry used to light up a small fluorescent light that is the actual light source for the display. The TFT display itself doesn't produce it's own light, and if you point an external light source to the display and see program windows & other things the display itself is fine. Your problem can be solved with relative ease, but only in a computer service because it demands some components to be changed.

Shine a flashlight on the dark screen to see if you barelysee the icons on the desktop. If so, then the LCD Inverter is bad.
Plug in an external monitor and see if the display shows up on it. It can beany kind of monitor even the old big fat crt monitors as long as it has a vgacable to connect to your computer's vga port. If so that proves yourvideo card is ok. The video will show on most systems when you rebootwithout you having to do anything. Some systems will require you to hit the FN(Function key) + F1 thru F12. Hold down the FN key then hit the correctkey for displaying on the monitor (F1 thru F12). The correct key willnormally have CRT/LCD on it or it will have the icon of a display.
If you see no icons by shinning a flash light and the external monitor works,then your screen is bad. If you see no icons by shinning the flash lightand nothing shows on the external monitor, then most likely your video card isbad.
In all likely hood, you have a loose connection or a worn LCD cable. This is a common failure in all laptops. If it is a loose connection, re-seating the connectors on both ends of the cable will cure this. If the cable has broken wires in it, it will have to be replaced. i would suggest a knowledgeable person or pro to tackle this for you.
yes what u need to do is that connect the external monitor with the laptop and if works fine with the external monitor then what u can try is that uninstall and reinstall the video driver and ten restart ur comuter and still if that doesnt work then replace the lcd screen...
