I have an Apple A1316 27” Display (non-Thunderbolt) that is exhibiting a weird backlight issue.
When first plugged into a computer, when it receives a signal, the backlight flickers briefly but fails to stay on. Otherwise the monitor works fine (the computer thinks another monitor is attached, I can see that it is displaying using a flashlight).
I tried turning it’s brightness all the way down before connecting it. When connected, it flickered, then stayed on. So it seems that it can barely muster enough energy to turn the backlight on, but once it’s on, it’s fine. Other people have had issues with no backlight ''after'' a period of functionality, my issue seems to be kind of the opposite.
What should I start testing on this? I’m leery of the power supply, but I don’t know where I might begin.
