1. un attach the bottom brown ribbon FROM THE PCB, NOT THE SCREEN by desoldering the contacts.

2. this way you can open up the LCD to expose the white ribbon without stressing the corners too much
(which is what seems to happen when I have tried to do a backlight on a perfect screen then came up with dead pixels)

3. Lay the LCD flat so that it is parallel with the PCB on a flat surface(no static!)

4. Like the guy replying if you read the link above, use gentler heat to reattach the ribbon

5. now reverse all these steps by reattaching the brown ribbon to the PCB and check to see if it works.

Like I said, this seems like way to much trouble but it might be worth checking out, think Im gonna pull out one of my damaged LCDs now and try it!
