Titel:

Won't Boot Past Apple Logo, White Screen, HELP!

Tekst:

I have a late 2006 24" iMac with the NVIDIA GeForce 7600GT, 256MB.  I recently have a problem where it doesn't boot past the white screen with the apple and activity circle.  When they disappear, I am left with a white screen.

I booted into diagnostics and got the error code: 4SNS/1/40000000: TG0H.  Not sure if this is the problem or not but I thinking the video card is the problem or a sensor on the video card.

Under diagnostics, when I pull up the Hardware Profile, it knows the resolution and memory size of the card but lists "unknown video" under video type.  I did all the reset stuff and tried booting from the installer disc, etc...  No luck.

I have replaced the main logic board and I still have the same problem.

Now the problem is, I can obtain a new video card, no one seems to have them in stock and say they are on back order from Apple with no date as to when they can get them.  What else can I use to get this thing running or does anyone have any other ideas as to what the problem could be?  Thanks in advance for your help.
