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. -- Jim Scott -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
