Forget the clock, that should be an easy fix, later.
Does 13E scan in correctly?
Does 3E scan in correctly?
I would try setting A to Astra 1 19.2E and everything else to not connected, then try a blind scan, and see what channels, if anything, you get, check names, and frequencies, against lyngsat, or kingofsat.
Then se A to not connected, and B to Astra 1 19.2E, and try scanning again, then just with C set to19.2E, and then just D set to 19.2E, and see if any of them pick up the correct channels, for 19.2E.
A lot of satellites are discontinuing DVB-S, in favour of DVB-S2, and future 4K channels.
