I was just setting up my P4P+ for a morning shoot and I must have touched the sleep button on top of the built-in display. The screen is now dead and won't turn back on. Any clues? The manual says to hold the button down to restart but this isn't working.

Sorry to hear that....It was my first 'What If' question i asked before deciding on the P4P and not the +. They offer no work arounds...so you're forced to buy a brand new RC ...soley because of the  tablets DJI proprietary nature.

It's doesn't come back on after powering down and back up the RC?

you can try something but don't know if will void warranty: open the RC and disconnect the battery, leave it for 10-15 sec. and then reconnect. Maybe it helps don't know.

If i open the RC I'll void the warranty.

Swipe the screen from the bottom up , you should see an arrow press it and go back to the home screen ??? Works on mine

I just get a black screen when I power up. Nothing at all on it. Tried swiping in all directions. Also tried a HDMI monitor but it said no signal from the P4P+ controller.

How does this case ended?  I´m on same situation.
