I don't understand yet, but maybe I'm getting closer:

You don't have a URC-7730 remote?

You have a device (a phone?) together with a program (Psiloc) that can send IR signals using LIRC files as a source?

You want to use that device as the remote control to operate your TV?

Your LIRC file for the TV has working codes for power and 1 to 9, but not for other commands?

How did you find those working codes for power and 1 to 9? The original LIRC file you linked has the standard signals 0c for power and 01 through 09 for 1 to 9. You seem to be saying those don't work, but 20 for power and 11 to 19 for 1 to 9 do work.

I haven't seen any data on IR signals for Altus TV's. But there aren't many signals available in RC5 device 0. I think your easiest course is to just test all of them to find the missing functions.

I expect all the working functions will have LIRC data values in the range 1000 through 103F. Maybe the range 1040 through 107F will be used, but I doubt that and I strongly doubt any signals outside those ranges will be used.

Your file lists 1010 for "-/--" and 1000 for '0'. You seem to be saying neither of those work. Since 1 to 9 are 1011 to 1019, I'd expect 0 to be either 1010 or 101A. Did you test whether one of those is 0?

If you aren't used to working in hex: There are sixteen digit values instead of the usual ten. So the number after 9 is A, followed by B, C, D, E and F before increasing the digit to its left. So the number after 1019 is 101A. The number after 101F is 1020. I hope those examples tell you enough to be able to count from 1000 to 107F (which range covers all possible signals of RC5 device 0).
