Hey,
I'm trying to make a diy projector usnig a 15" lcd monitor (http://www.futureshop.ca/catalog/proddetail.asp?logon=&langid=EN&sku_id=0665000FS10062104&catid=) and an overhead projector.
I tried taking apart the monitor yesterday. However, after takign apart, I checked to see if it was still working, and the bottom 1/3 was working, but the top 2/3 was mostly black with some random lines of green, yellow and blue.
Where did I go wrong? Did I put too much flex into the screen?
I know that when I powered it up for the first time after taking it apart, that two of the three contacts that look like they usually make contact with the metal frame were not touching the metal frame.

dude, i'm with you man.
YOu have to be REAL careful with these things. My very first lcd i had working and apart, put the lcd on my projector, and was in heaven cause i had it working.
then, i put my lcd on my bed to clean up the floor, then i leaned my arm onto it by accident with just 2 pounds of weight or less.
and sure enough, when i tried it again, it had vertical lines all over.
then......... my next TWO lcd's i bought did not work out either, one i tore the flimsy *** paper circuits on the side because samnsung in their infinite wisdom use a **** load of foil paper and glue, then the THIRD lcd was one that could not be used on an OHP due to the position of the ffc cables and boards.
thanks GOD i found this website so now i can buy an appropriate lcd monitor and BE CAREFUF this time taking it apart.
oh, so for you're answer? you're screwed. throw it away and buy another one.

I just bought the same monitor, from Futurshop as well. Best Buy was selling it for $30 less, so I got Futurshop to give it to me for the same price.
I got it stripped, and was dissapointed to see that I needed the FFC extension, but other than that, it went ok. My screen still works fine, and it has very good colour and contrast.
As far as your 2/3 screen going black. Too bad. The reason I bought this panel was that I killed my perfectly good BenQ FP531 panel (very easy to strip, NO FFC issues!!).
You CAN repair the lcd panel. But, you need to dish out $100US for a roll of z-axis anisotropic pressure sensitive adhesive that will re-bond the FFC's to the glass. But, that's hardly worth it when you can buy a new panel for just a bit more.

Thanks for your replies...
I probably wasn't really clear in how i phrased my question.... I wanted to know what I was missing out on my first attempt (aside from cracking the lcd panel)
What exactly are the FCC? (I know.....i sound really dumb) would anyone like to just briefly explain, or point out in a picture? I don't seem to understand what others have posted in other threads.
And for that matter...how do you extend the FCC?
Thanks again,
Jeff

FFC - Flexible Flat Cable
The FFC is question when making a DIY projector is the on that connects the board on the side of the lcd panel to the one on the top of the panel. When it is installed inside of the monitor case, the circuit boards are on the back of the CCT (backlighting panel). When we strip the panel out and use it for a projector, these circuit boards are in the light path, and need to be moved out of the way. But, the short FFC restricts their movement. This is why we need an FFC extension. Thnk of it as an extension cord. It really is only a short piece (6 " or so) of FFC with a socket on one end to allow you to extend the FFC on the panel so that you can move the circuit boards out of the way.
The Metro panel you (and I) bought needs the FFC extension. I had a BenQ panel before this, and it only had the one circuit board on the top, so there was no need for an FFC extension.
go to www.lumenlab.com and check out there stores link. They sell FFC extensions. I believe that you will need the 16 pin unit.

cool.... thanks! is it okay if i PM you if i have any questions about taking apart the next unit?
that would be fine. I just ordered my FFC extension a few days ago and am waiting for it to arrive.
So far, I am quite please with the image that I am getting from that panel (and my pj setup). And it passed the WAF. (Wife Approvement Factor)
