Hi there, Some time ago a friend of mines screen of his iPod Touch 4G stopped working. It showed a lot of dead/stuck pixels in a group. Moreover, the rest of the screen remained totally white. Now, those dead pixels have disappeared and sometimes small grey lines form and go away. When viewed upon from a very flat angle, the UI is visible and responds to touch. The device is controllable, but you cannot see what you do, because the screen is totally white. Rebooting/restarting several times over the past few weeks haven't resolved anything. Does anyone know what could cause this? It isn't as simple as the screen that is broken, since you can view the UI very faintly. Thanks. Edit: Also, the screen isn't physically broken. The glass isn't shattered or teared.
