Possible Power Supply issue?
Hello everyone. Long time lurker, first time question asker. This community has been great to me over the years. I mostly replace iPhone screens and other easily addressed issues on iPhone for family and close friends of family. So this community has been very helpful with some of those things.
I recently was given a 27in Cinema Display from a customer of mine (from my actual job). He was about to throw it out because "it's just a black screen". I told him I'd take it off his hands. I was originally thinking it was just the back light that may be broken. However, after getting it home it seems like a possibly power supply issue. When the monitor is plugged into a power outlet it won't even power up a Macbook through the Magsafe cable. This is my first Apple display and it doesn't have a power button so I assume it just powers on when plugged in or when a device is connected to it?
For those of you out there that have repaired these, is the power supply a likely culprit? I'm getting 120v on the cable so that doesn't seem like an issue. I've read in a few places those can go bad.
Also, Macbook does not recognize a display connected. Thus another piece of evidence leading me to think the dang thing isn't even powering on.

Did you eventually repair the unit and was it the power supply? I have the exact same model with the same fault.

Hello , I am fixing up one for myself.
did you end up fixing this?
mine doesn’t power up the screen but when magsafe power cord connected to MBP it turns green light .
but NO responds on (USB sticks).
Hello, could you solve this ?! having the same issue (there is also a flash to the screen, like an attempt to display, when I first plug the display port on my macbook pro, but then nothing)

Power supplies tend to go. I'm very certain replacing it will solve your problem.
