I've had a similar problem with an RJ2 controller and ended up having the board repaired at a facility in the USA. Cost about $1200 but it came back with warranty. I still have that contact info if you feel that is the route you want to take.
hello,
do you have that contact information?
my tp is booting up to bmon screen that states the tp version is "unknown" or other times as "I". battery recently changed and no sw backup. waiting for a s rs232 cable to arrive to see if the routines and any other data can be salvaged.
