I tried stripping a DELL laptop monitor down but found that i was unable to get all of the wires out of the way for backlighting... Very unfortunate 🙁 . I was wondering if a desktop LCD monitor ( also dell ) would be any different. When I tried to shine light through the back of the LCD I found that there were a bunch of ribbon wires in the way and circuit boards that couldn't be moved... is there a certain brand of LCD that works better than others? Should I use a desktop LCD monitor?
Thanks for all the help,
nate

You can use either a desktop or a laptop. You just have to get the cables out of the way. There are things called FFC extenders. FFC cables are those ribbon cables. The ones that need to be extended usually have a clamp that can be opened. Check out this:

I disassembled a 17" Dell desktop LCD. This link shows you what I did. Is the 1900 a 19" LCD? If it is, you'll need the pro lens from Lumen Lab or some projection lens that can handle a 19" monitor. Good luck!

where can I buy one of those cables and how do I know which one to choose..? It seems like it'd be pretty tough to tell which number of pins I need. Just count them up?
They are called FFC ribbons and their dimensions are length of the ribbon and wire count. You can get them at www.lumenlab.com or you can go to an electronic shop (online or physical store). You'll also want the appropriate connector (it's a clasp that holds both the existing ribbon and the new ribbon together). They also have a pin count. Make sure they match.
Yeah, you literally count how many wires there are. An easier way is to get a camera and take a very close (in focus) dead on shot of the wires and look at it blown up on the screen. Easier on the eyes.

that's great because I wear glasses and I was pretty much screwed for counting lol... thanks a million you solved my problem!

is this the correct piece of wire.. I'm extremely new to this FFC wire stuff.. there's so many different types :-\

I built my projector around an IBM Thinkpad 600E laptop. I removed the plastic covers from the display (13.3") and unfolded the LCD panel from around the backlight assembly. Then I VERY carefully soldered fine wires to jumper between the ribbon cable and socket that come together when the LCD is folded around the backlight but are separated by about 6" when it is unfolded and laid flat. I built a wooden platform to position the LCD properly on the overhead projector and provide an adjacent surface for the base of the laptop, which remains connected to the LCD with another ribbon cable. I can project whatever appears on the laptop screen, including web sites I'm browsing or DVD's I play in the laptop's internal DVD drive.
It was painstaking work requiring a steady hand and a precision soldering iron but the results were excellent - a good sharp image at XGA resolution and 24-bit color depth. In a dark room, my 3M 9550 overhead projector (400W bulb) produces a very acceptable 96" diagonal picture on my surplus DA-LITE screen.
