We just bought a 2014 Cougar 330RBK. We have had it at home setup for a total of 5 days. The first issue is my landing gear switch quit working, then the "fancy" soft touch panel quit working well not...
I've got a 333MKS with the same problem. Disconnect shore power, then turn off main battery disconnect switch (thereby disconnecting the battery). Reconnect everything and you should have a working panel again.
