@ROGERW posted:MTH had the SAME PROBLEMS with getting parts for the proto 2 boards! That is the reason why they switched to proto 3....part availability, more functions that can be programmed into board and smaller size.
Apples and oranges. They replaced the PS/2 boards with a fully compatible replacement. That's not what is happening here. In order to make that a similar case, they have had to replaced the remote with an upgraded remote, not a smart phone or tablet from a 3rd party.
FYI, some of the parts on the PS/3 boards are already obsolete, try buying the common mode chokes on the boards for the ones that fail...
