Rogue kernel_task only when iSight/Airport Cable plugged in
Hi, so yesterday I removed the LCD of my MacBook. After reassembly, the Fan is running at full speed and kernel_task is massively slowing down the machine. This may be due to my disassembly, it is also possible that it is caused by an Update (right now it's on 10.13.2).
Upon further investigation I noticed that when I unplug the iSight/Airport cable, it runs fine. I also tried plugging the Airport cable into my old 2008 MacBook, which works fine. The other way around works fine aswell (plugging the old MacBooks Airport Cable into the 2010 Macbook).
Additionally, I tried unplugging all devices from the Airport/iSight Cable (Airport, Camera, Bluetooth Board), and just plugging in the Cable without the devices yields the same result.
So in conclusion, it seems to be down to the cable, which however works fine on the old MacBook. It could also be down to a kext error, which to me doesn't explain why the issue persists when only the cable itself is plugged in.
If anyone has an Idea on this curious Issue, I would be thankful. The only solution right now seems to be pulling off the display glass of the old MacBook aswell and swapping the cables/airport cards/bluetooth board altogether, which I'd rather not do.
Thanks in advance

Questa è una buona domanda?
Were you ever able to solve this? I'm having the same issue.

This happens if either the cable is slightly damaged (when removing the glass) or the camera PCB under the glass is damaged. Replace either the cable and/or the camera board and this will resolve the issue

I figured out what the issue was.
I never did anything with the cord before the problem started though. I believe I had a little water damage. I thought the logic board was screwed after it happened, but I replaced it and it still had the same problem (kernal_task taking up insane amounts of CPU). I randomly came across a thread where a guy had the issue, but not from water damage, from changing his display. He said unplugging the camera cord fixed it, and that worked for me as well. You think the only way to use my camera again is to change the cord? I tried cleaning the connector with alcohol, but that didn't work.
