I have a G5 1.9ghz I-sight, and of course, it has the dreaded lines in the LCD problem. also had the random shutdowns and no bootups. I cured that problem by reflowing the IBM chipset BGA and the video BGA. those problems gone, but the lines i believe is from a bad LCD.

the question here is, it is using an LM171W02-TT panel. as its the isight. everyone said you cannot use the version 1 and version 2 imac g5 LCDs in the version 3 at all. Is there a reason for that? why not?
