[TenTec] Master Reset on power up

[AE5QU at aol.com]

My Orion 2 has worked flawlessly for many years. However very recently when 
 the rig is powered up it goes into a master reset (displayed on the boot 
up  screen as if it were intentionally done). I reloaded the latest firmware 
as  well as actually performed a ram clear followed by a master reset. No 
help. The  rigs parameters can be reset up after boot up and it does work 
fine, however on  the next power up, the same thing occurs. Any Ideas???
 
Thanks,
