Aloha! Due to some crazy events, the repair of my 27" iMac Mid 2010, A1312, EMC 2390, iMac 11,3 revealed that I needed additional parts. The new power supply did not fix the black screen - what appeared to be an obviously burned out resistor was not the problem. The video card was. Now, weeks later I want to put it back together, but I am at a loss in regards to where these steel pins belong and why they fell out in the first place. I had bought this iMac (refurbished) from the Apple store and found now out that the graphic card had been replaced in a half fast way. Very sad and I can only wonder WHERE Apple has its defect returns refurbished. Anyways, the three conical steel pins are kind of self explanatory, but I would like to get them back in the way they should be. I can’t believe that they are loose ex factory and one can see something like double sided tape at their bottoms. The real problem though I have with the cylindrical pin. It actually looks like a tiny battery and the only place I can imagine it goes is next to the iSight module, left of the camera lens. I can see what appears to be contact pins, but need to be sure if the cylindrical flat (battery-like) pin goes in there or not. Small mistakes can have costly consequences, so I decided to ask the iFixit Answers/Ask section. Thank you very much in advance. It is imperative to get my iMac back working, because I ought to finalize my book and it’s on the iMac. As we say here in Hawai’i: Mahalo nui loa! (Thank you very much!)

The ones that have a cone top look like the index pins on the frame to align the display assembly (along the left & right edges). I’ve never seen them pulled off before did your system get a bang?
