So I was taking apart my laptop to combine it with my Wacom Graphire Pen Tablet to make a DIY Cintiq. I got the screen out of the case, and had it so I could freely move it anywhere I wanted, of course still constrained by the wires. So I was REALLY careful, because I didn't want to break my laptop screen. I peeled off the tape on the back of the screen, and didn't press anywhere where it said not to. I turned on the laptop, and when my desktop came up I turned the screen towards me. I was also very careful where I was grabbing the screen. So I was examining it, trying to find out how to get the metal case off, and I apparently touched something important and damaged it somehow. As a result, the pixels on the screen started to turn white! "It was spreading" kind of; expanding out to the rest of the screen from the corner/edge that I touched something. So eventually the entire screen was just white pixels. I turned the laptop off, then back on again and it still displays only white pixels. I can tell that the computer itself is working fine, by the sounds the fan (which is moderately loud) was making. What did I do, or how can I fix it??

Honestly I am not very sympathetic to your plight. You MIGHT find something here. http://www.google.com/search?source...

Well thanks for the link, but it didn't help me much. The problem is external, and there's no software or ANYTHING that I could run to fix it, because I can't see anything on the screen.

Did you look at all the ideas. One I have read involves rubbing the pixels. Google How to repair dead pixels.

this sounds like more than dead pixels - your LCD is toast. if you don't know what you're doing, "being REALLY careful" might not be enough... that's not to say that you should just sit tight and never do anything. we live in the information age - the entire accumulated knowledge of our species is now googleable. so you can research before you break more hardware. it's kinda like, "measure twice, cut once..."

The pixels aren't dead, and the LCD works [and by works, I mean outputs light of some sort]. It's not getting any color/information input from the actual computer, i'm assuming, or something like that. The computer itself works because I can use it just fine hooked up to an external monitor, I've recently discovered. However when I turn on the laptop all it shows is white pixels on the LCD.

if the computer can send accurate color and image information to an external monitor, that would suggest that the laptop graphics are fine. i could be mistaken, but i'm pretty sure you can bust an LCD without busting its backlight, so you'd still see white light but no colors or shapes.
