Buttons are registering intermittently?
If you find you are having to press hard to register an input I would recommend ensuring the board is not offset and cleaning all the buttons contacts and membranes with isopropyl alcohol. Sometimes a little more than a rub with alcohol may be needed. I prefer the lightly rub the area with scotch brite prior to cleaning.

I have prepared a short video showing how much difference a proper clean can make.
My device will not power on with batteries

Please ensure the battery polarity is correct. Not all battery connectors are the same. Double check the ensure the red battery wire is going to the + pin on the Power Board.
