Re: my display lcd suddenly fadded to a faint display .
I really don't know if it will work, its been a long time since I had a PC, sorry if my possible solution sounds stupid
Check in Properties, in the section of battery or display, there's an option (i think) which fades the display when the battery is at a certain level.

connect an external monitor and check how is the display,if the display is fine on external monitor,then it would be your LCD OR VIDEO CONNECTION OR CABLE NEED TO CHECK . If you are getting the garbled picture on the external monitor also it could be
SHARED MEMORY AT FAULT( If the laptop uses shared video memory (part of the main memory is used
for the video purposes), it's possible that you have a faulty RAM
VIDEO CARD (if the video card is discrete replace take out that and
check the video with integrated video card and if the video card is
integrated then you have to replace the mother board)
The problem youve discribed does seem to point to your back light has failed on the laptops lcd display, i dont know exactly how this would accure just using a projector though, go into bios again and try loading factory settings.
This problem could also be the inverter if you cant make out even a slight image on the screen.
On the second Thinkpad laptop, that doesn't show a display with an LCD screen. Plug a VGA monitor into the VGA port on the back of the laptop. Hold the Fn key down, tap once on the F7 key (Toggle your display over to an external monitor)
Give the VGA monitor a few seconds to come on. (It's a VGA monitor)
Do you have a display on the external monitor? No? You May have a bad GPU then. (Graphics Processing Unit,
Fix? Change out the motherboard. Possibly Ebay has one, dunno.
VGA monitor has a display? Then you may have a bad Inverter. The Inverter provides power for the LCD screen. Inverters go bad.
Are both Inverters the same? (Laptop to laptop) BE SURE. The Inverter MUST match the LCD screen! Check the numbers on both Inverters. If they are the same, switch the good one over to the 2nd laptop. See if you have display now. No? Then it's the GPU.

The Cold fusion lamp in your LCD and or the invertor board for the LCD could be bad that is the reason why a faint image . As for the external monitor you should enable it by the Fn+F5/F6/F7 key by pressing it twice at boot up before windows is fully loaded - this to ensure that the external monitor works with your laptop . If the resolution setting and frequency is not comaptible with external monitor you connect then you wont have display on your external monitor . Start windows in safe mode .
Well yes BUT if it is a problem with the LCD then you would need to replace try plugging an external monitor to see if the sizes are normal if they arent then it is definately a problem with the screen resolutions.??
