Have a PRO for 3-4 years. Just recently the tuner seems to have failed. Confirmed that a valid CATV signal is on the coax by replacing the SB with a TV. Thought that might try reloading the box firmware but am told that it is running the latest (1.4 something I think) so can't reload to see if that jogs something. Have done several push button resets but to no avail. When I go into setup I cannot do anything with the coax input as it says no signal. Have a composite video signal from a camera and that works just fine.
Any thoughts other than purchase an external TV tuner or find an old VCR to connect to an used used port such as S-Video?
Thanks in advance.
