Conclusion
[ ]Not for the faint of heart and recommended only for someone who has a full day free and isn't afraid to tinker. Since the 2009 iMac is out of warranty and non-functional with a problematic video card, there isn't much to lose by attempting a video card repair. And while I cannot guarantee the "oven bake" method will work in every case, it did work in mine and in the case of many other people whose stories I have read online. Indeed those stories were inspiration for me to attempt the same repair. Even if one does not wish to repair the video card, this video still shows how to remove the logic board and video card and put them back in place.
