My Display goes Black after 3 minutes, USB and MAG safe still work
I have a TB display that has been giving me some issues for a while and i have decided I’d like to fix it. Mainly i know it’s either a logic board or PSU issue, but don’t know which one I should replace.
My TB display turns on and after a few minutes the display will go black (no, not just the backlight). The hub still works (all my usb devices), my macbook still recognizes an external display is connected, my speakers still work, and magsafe still charges during the blackout.
If i unplug the display from the wall and back in, it usually will start right up, and then shut off within 3-5 minutes.
I have tried a different TB cable, same issue.
Do you guys think it’s a bad PSU, or a bad logic board?
Ist dies eine gute Frage?

Aim a flashlight into the display at a sharp angle are you able to see the faint image of your desktop icons?
If you do, then the backlight logic is in question.

No, it's not the backlight (as i mentioned in the post)

So you tested out as I described? If not give it a try, you might be surprised!

Yes, as well as done all of the other suggestions mentioned in other posts. my theory is it's overheating and sleeping the display.
