Hi All,
My first problem was faded numbers, this was fixed by fallowing info on a Youtube video.
My new problem is
After programing the six channels, day complete shows up.

Then I press ok to accept, the window just shows a line of dashes and won't go any further.

When I switch to Auto the programmes 1 to 6 come back up and box one flashes as if it wants to be programed again.
If I go through the programing again while on auto the same happens, day complete and just lines and will not go any further.

Unit works on manual, unit about six years old, had no trouble before. batteries are new.
All views welcome.
Regards,
Jimmy.
