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

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.
