Apple Display A1267 AC Plug Must be Repeatedly Plugged in to Power Up
Apple Genius found a broken wire in the Mini Dvi AIO cord so I replaced the AIO and then Display power cord since there were signs of cracks. Display worked flawlessly for months. Now it’s doing the same thing, A flicker when plugged in so you know when to enter pword.
Then, you need to tease the wall outlet with the display power plug until the display powers up. Apple Genius lady giggled a lot when I told her that with a straight face.
Following advice and posts, I did replace the logic board, and then PSU with known good parts. Display is fine on restarts, not on cold starts. Hot corners off, Pram reset, etc.
I inspected the boards for burnt spot with what I had. An iPhone Macro Lens and an LED magnifying lamp. Nothing burnt.
Display is recognized by two Mac mini’s.
Could this be simply an AC Power Inlet issue and how to check?
Thanks in advance.
Is this a good question?
