Display shows strange, bright colours - LCD defective?
A few weeks ago the screen of my iPhone 3GS suddenly started to look strange (see picture: http://img529.imageshack.us/img529/2599/...), eventually a backlight problem?
It goes to normal sometimes by blanking the screen and turning it back on using the power switch. At the beginning this worked after a few tries, meanwhile even after 50 times or more it still does not help.
Even if it does work, as soon as the screen gets turned off, eg. during a call, it will show the strange colors when turned back on again.
Does this mean the LCD is defective or could it even be the logic board?
As the "ifixit Display Assembly" will be more than $160 with shipping and taxes I don't really want to just try if a display change helps...
I would be grateful If someone has already experienced the same problem and can tell how it could be fixed.
Thank you for any help!
