Hey, thanks for the tips!
I have tested the power, left and right buttons with an improvised continuity tester (3.3V power source, resistor, LED). Confusingly the LED powers on regardless of button state, but there is a very clear increase in brightness when I push a button, so let's assume the method is valid.
The right button (page down on PB614) is stuck as ON, as nhedgehog suspected. Can it be fixed?
