My old PowerBook's screen went all green with no contrast. I can just about see stuff...but. it really hurts your eyes. Pity 'cos everything else seems to work fine In fact my 7 year old, just uses( used) it for drawing and playing her 9.9.2 cd roms. I 've tried re booting.... leaving it off for several days... and staring nastily at it and shouting.... its still all green. Any LAST ditch efforts I can try before sending it too that big Applel in the Sky.( its a real old P/B G3 with only 4 Gb of hard disc) Thanks for ANY Idea's...my 7 year old would REALLY appreciate it.
