2 Display power cable is bad?
I replaced the display on the iMac and when I reconnected everything I noticed a flicker on the screen and that the display was not a bright as the previous one.
After a day or so the display went black and did not come back on.
I figured that there was a loose cable, but when I reopened the unit everything was secure. I powered up the unit as a test and found that the display flickered when it was lowered into place.
I soon realised that every time I moved the display up and down or touched the display power cable, the screen goes out.
I can’t see any damage to the connector on the motherboard. The display power cable end and sheath seem fine, no obvious damage.
Because I can only recreate the problem by touching the connector end of the cable I don’t think the display itself is bad. And like I said, the motherboard connector seems fine also.
Can I get a tv repair guy to swap this connector with the one from the old display, and should the spliced cable be soldered? Finally, would soldering cause any damage to the screen or would the heat dissipate before it can get to any of the components in the display?
Thanks for any help you can give.

Hi @danj
Thanks for taking the time to respond. I added the photos you asked about.
I hope it helps.

Sorry Ted can't see anything here. Can you get in tighter and take some pics of the connector on the logic board as thats more likely the area that is damaged. The tighter and in focus you go the better!

Will do @danj
I will have to get the system back from my friend, he is using an external monitor to get him over a working hump. He is a writer and is behind on a few projects because of the display issues.
I will come back to you as soon as I can.
I was hoping that the cable was at fault and not the logic board.
What I will also do is attach the old display and see if the problem of the blacking out persist when we touch or flex that cable.
Cheers.
