Hi, My Samsat CA100 super (Ali C) could not not boot correctly and still display "On" after booting. At first, I experienced a "run" problem as a consequence of loading a new frim. So I cleaned the receiver and I tried another firm and got some error message. At last, the loader didn't even recognize the receiver and "test serial port" is displayed indefinitely. IS it a hardware problem or do I have to apply a Jtag?
