I’ve been having bother powering the Picade successfully from the official 2.5A pi charger, when I hit the power button the screen powers on, displays no signal and retropie never appears on the screen. (I’ve also tried with a 2.1A Apple charger but see the same result).
If I connect a separate power supply directly to the display it works as expected (its great !!). It does flash the large rainbow square right at the start, but after that I don’t see any indication that the Pi is not getting sufficient power (no warning icon in the top right).
Any suggestions on how to figure out what might be going on?
ps. as an aside the led in the power button has also stopped illuminating, I’ve not had a chance to dig into whats going on there beyond checking the cables as I have the Picade in the office at the moment with no access to a multimeter.
