Re: iMac G5 1.8G - Fresh caps, but not quite there...
Ahh the video culprit.
"The logic boards sometimes gets all three diagnostic lights lit...but there's no video. The screen remains black. I disassembled & then reassembled both & was able to get one to boot fully (fans running a normal speed, hard drive spinning up) minus any video. But now neither one will light the third LCD green light or fire the hard drive/fans."
I am the original poster and this is what I found when I rewired the board a second time and got video. I experience the...

The PS was factory new 1 year ago. The Logic Board (Mac for Motherboard) had 2 visible bad caps which led to video distortion and common among this gen of Macs.Re: iMac G5 1.8G - Fresh caps, but not quite there...

I have checked the connections several times with nothing loose or crimped. Its as though the board is working but failing to properly power or video feed the lcd. I get a dimly lit glimpse or two of the os loading and my desktop before it fades to black. It's possible that the LCD is hosed by coincidence or something else on the board is not working correctly. Oh the joy of an all...

Wort case scenario is that I get an external video adapter
