Hello - I have this same issue and tried to complete this repair, but the VSync connector on the new LED Driver Board is different. Has anyone had this issue? Know of a reason why? Any help would be appreciated.
Thanks
I have found two different inverter boards in the 27” 2011 iMacs. One, like shown here, has a 4 pin connector on the top edge that a small connector with 2 wires coming directly from the LCD panel plugs into. The other has an 8 pin connector with a cable about 16” long that goes from that connector to the 8 pin connector on the logic board labeled BLC_ACDC. I’ve come across this configuration 2 or 3 times, out of 40+ iMacs I’ve refurbished.
The inverter board with 8 pins has a part number of V267-E02HF and they sometimes show up on eBay. The cable has a part number of 593-1435 and they’re impossible to find.

With the V267-E02 inverter installed, I have seen panel LM270WQ1 (SD)(E5) used instead of the normal LM270WQ1 (SD)(E3).

Is there a chance the cable is bad? I just replaced my logic board and now the PC is up and running normal but the screen is dark, I see the desktop if I shine a light on the screen.
How can we test if possibly the cable is broken?
