iMac Vsync Cable Mismatch

My iMac 27inch Mid 2010 2.93GHz Core i7 (Model A1312-BTO/CTO EMC: 2390

I replaced the LCD Power board and now I have a mismatched VSYNC cable. The cable coming from the LCD is a few wires with a 4pin connector unlike the other temperature cables. The LCD board appears to be a ribbon cable?

Does the LCD panel have a way to remove the VSYNC cable from the other end? and if so how would I go about attaching the ribbon cable. Or is it unfortunate that i would just have to buy a new LCD power board that matches the VSYNC cable?

Thanks in advance for your help!

jea508 what do you refer to as the LCD power board? Do you mean the LED driver board or the graphics card?

Oldturkey03, Maybe I miss typed what i meant. It could be called the LED driver board. It's the board on the bottom left, about 6" long and about 5" wide. It's the board you are supposed to plug the vysnc cable into on the iMac.

Hi Justin,

I have just done the same thing. Currently the iMac is working without it connected. Did you ever find an answer to this problem?

You should not have a LED board with a ribbon cable. This is what your board should look like.

Old Turkey, the board is infact the same board, but with a different connection for the vsync. I read somewhere in one of the ifixit.com instructions that the vsync cable could either be a ribbon, or a set of wires. My iMac screen has the set of wires coming from it with a 4pin connector, i fear the LED board has the ribbon end.

This is the connection I see when I open the iMac in the link below (I dont know how to add pictures to comments but I did add a picture to the original question if you don't want to click that link). However, there are "wires" from the lcd panel which has the 4pin that would fit the socket in the picture you provided.
