Chosen Solution
I am living in Paris, and my video card is not working anymore on my imac. I need to find the Apple part 661-4663 (or 661-4664, because i can upgrade it). Do you know where i can find one, serious seller wanted of course. And where can i find a tutoriel to do it? Thanks a lot.
Prices have remained high on this GPU because of supply and demand. They failed a lot. We have repaired four of them just this week after we found out how to do it and got the rework hot air machine to do it with. PowerBook Medic is selling it for $150: http://www.powerbookmedic.com/parts/661-… If you want to take the time and learn how to put it in, here is a guide that will work: iMac Intel 24" EMC 2267 Graphics Card Replacement eBay is offering repair service for $120 here: http://www.ebay.com/itm/APPLE-IMAC-24-20… If you want me to give your’s a shot I’d charge $95, you pay return shipping. No charge if I can’t fix it. I know this is a little SPAMy but I don’t do it often ;-) And it is a very viable repair option. And sure beats the prices that Dan’s links gave. No offense meant Dan. (After all I emailed you on how to do this repair last week so you could do it!) Or you can do it yourself with some hours of study, and this equipment: Board Pre-Heater Hakko FR-870B Loc-Line Kit Hakko 999-205-02 fits FA-430 Smoke Absorber http://www.tequipment.net/Hakko/FR810B-0… Solder Leaded 63/37 Rosin Core Omnivise Board Holder Hakko C1390C Arctic Silver Thermal Paste Arctic Silver ArctiClean
Sadly IFIXIT doesn’t have a guide specifically for your system. But! there is a user created guide for the next generation of iMac which is very similar to yours (Apple used the same design as your system). Here’s that guide: iMac Intel 24" EMC 2267 Graphics Card Replacement. I like The Book Yard located in Liverpool UK here is what they offer: iMac Alu 24" ATI Radeon HD2600 Pro 256MB (08) : Recycled - Apple PN: 661-4663iMac Alu 24" NVIDIA GeForce 8800 GS 512MB (08) : Recycled - Apple PN: 661-4664
