Hey,[br]
[br]
I have the same issue. The screen went black. As mentioned before, this phone was heating a bit (while charging, usually or with extensive use of the camera), but it is still heating the same way as when it worked (not overheating, just getting warm). I have checked my battery, and it gives ~4V when disconnected. ⏎[br]

When it first died, it was just a screen; it seemed as though I could still hear vibrations and sounds, then it went off. The next day, I swapped screens, but it didn't boot up since placing a new screen (I have tested against the old one too).[br]

I think it would be useful to know what voltages should be on hardware test points/pins (and where to measure them), so I can measure them, and to know where the CPU and Memory are. ⏎[br]
