Hello friends, i was given an iMac G5 with a bad video card, it shows artifacts on the screen, and freezes on the Apple Logo. I need to reflow it with hot air, but i can't locate the video chip, can someone please tell me where it is located?
Under the heatsink, it should have ATI or NVIDIA -logo on it (or in NVIDIA's case "GeForceFX" is atleast printed on the chip. If not, Google pictures of Mobility Radeon 9600 or X600 or GeForceFX Ultra, it's one o f these chips.
Some Intel iMacs were sold with GMA950 which I think was integrated to the chipset itself so there is no additional graphic chip to look for, I'm not sure about this.
