I'm going to replace a display in a 17" G5 iMac 1.83 for a friend.
this will be the third one for this machine the first one was done
by Apple Care at 30 mos, it lasted 7 mos just long enough to be no
warranty. So this will be the third one I was wondering if this is
a problem other than the display itself? The displays begin
growing lines vertically in wide patches.
Could be the bad capacitor problem; could be a bad LCD. If you have
an identical second iMac you could swap the LCDs to see if the
problem travels with the LCD. That's what I did last month with an
iMac G5 17" (pre-ALS) that had several groups of vertical lines. It
was the LCD, and after a replacement everything's OK. OTOH, I've
had iMac G5s with vertical lines where the problem was bad
capacitors *and* a faulty inverter. I've also seen munged up LVDS
connectors on the back of the LCD. So pretty much anything is
possible.

I don't have another machine to test the display in so I'll have to
put in the new display and I guess kinda hope it's OK, can the
display work awhile and then crap out due to a capacitor problem?
Also can the Apple ASD pickup this defect?
