Erratic button function

[Cwwatters]

Dynon 180 with 130 h of trouble free function over 2.5 years but recently (1) the buttons are not functioning/ responding, to cycling of the pages and
(2)after setting the barometric pressure the altitude will wander randomly up or down.
(3) I can only turn off the dynon with the master switch ie no response to holding a button to shut down the dynon.
