A1407 Display won't turn on, but USB ports still have power
Hoping to find a solution before donating this beautiful display. My friend gifted this display to me, it worked for one week with my M1 MacMini w/ USB-C thunderbolt adapter, and then the frayed cable started causing issues, I would wiggle it to turn it back on; it worked for another day. And then the next day it would not turn on at all.
When the thunderbolt cable is not plugged in, I noticed that the USB ports on the display would have power to them(can charge iPhone, but no data connection), but once I plug in the thunderbolt cable, the USB power would go out.
Since then, I have opened up the display and replaced the thunderbolt cable. Again, the display would not turn on, but all the USB ports have power delivery, no data connection.
Thinking it’s the logic board, I had just replaced it with a working unit off eBay. But I’m still having the same issue. Hoping to try my luck here. Could it be the PSU? With the amount of time and money spend on repairing this display, am I better off getting a new monitor?
Thank you in advance!
