Cable from power button broke during hard drive replacement.
I was in the process of upgrading my (iMac 21.5" 4k) and whilst I was removing the speaker (for easier access to SATA cable) the cord joining from the power button to the logic board (which travels along the left speaker) broke. I was not applying much force and am very surprised that it broke. This means I am now unable to power up my iMac. Is there anything I can do to replace this part or somehow rejoin the wire? Any information would be GREATLY APPRECIATED!! (Even if it is "there is nothing you can do")
Thanks very much!
