Can anyone tell me if the video card is soldered on the the iMac late 2009

My screen goes completely black I have done every test imaginable, with other info on the forums my video card seems to be faulty. I am apparently not the only one with this issue. So as a last resort I am possibly going to do a repair. Can anyone tell me if this video card is soldered on the motherboard or does it plug in.

It is a late 2009 27" iMac with the EMC# 2309

Thanks Greatly Appreciated!
