Trying to find a flat screen for my final project, I found one on the trash that seemed ok. It has the VGA connector crashed but I used the DV and I realised that it has also a crack on the display. As it was useless (for normal purposes) I cracked it a bit more, pushing the liquid crystal move along the cracks with a screwdriver.
Pressing around the cracks random lines of pixels appeared, and also some parts of the screen changed brightness suddenly. Quite amazing!
