John Rougeux Member # -1 Registered: 11/06/08 Posts: 5366 Loc: Louisville, KY	My in-law's iMac G5 went belly up the other day. No immediate known cause, but when I looked at it, I knew that I couldn't fix anything on it. Would this be the video card, motherboard, or ? Here's the Apple on startup. Notice how it's not solid color and has like a split to it: Click for full size And here's the furthest it gets. It won't eject the CD I put in it. I can't boot it into anything else or off of a CD/DVD that I can tell. Click for full size

That should let you know if it's just the vid-card or if it's more. _________________________ http://davidbearphotography.com/ ==== It appears that autocorrect has become my worst enema. ---

The video card isn't expensive but it's the last item on the take apart list. Like Michael said, some models had the bad capacitors. Take the back off and see if any caps are bulging or leaking, but I don't think that would affect video, it just kills the machine. _________________________ AppleCentral Trivia MM-MCF Trivia Call the Doctor

Been a little while since I did this but after you have it mounted via FW Target Disk mode go to preferences and Start Up Disks and select the one on the "bad" machine and restart. _________________________ http://davidbearphotography.com/ ==== It appears that autocorrect has become my worst enema. ---

NG4, there is no option to go to preferences or anything in FW target disk mode. It only displayed the firewire symbol and then the HD appears on my iMac.

John Rougeux Member # -1 Registered: 11/06/08 Posts: 5366 Loc: Louisville, KY	Ok, I am wrong. Apparently it does boot up into Safe mode now. I'm now logged in, but the graphics are horrible. inserted and now trying to boot off of Hardware Test mode. Edited by John Rougeux (09/07/10 04:41 AM)
