As far as changing colors of the screen, you can do this:
First archive all entries. Then, type [MODE], [ALPHA], [ S], and [ENTER]. Press the [ON] key to escape from the counting numbers. Keep on pressing [Enter] until you see a number on the screen. Finally, pres [ON] again to escape the Test Mode and clear your ram.
I'm not sure if that will help any, but I hope your screen can work again.
EDIT: I also found this.
