I looked in the manual, and it appears that the IR protocol is NEC1, device 0.127  (127 expressed in hexadecimal is 7F).  Other Curtis TVs use this same IR protocol.  The diagram of the remote in the manual then shows all the function numbers for the buttons, so we know each IR command.

However, I'm not aware of any cheap universal remote that has this set of commands built in.  You can program a RCA RCRP05B to control the unit, using setup code TV 1548.  The remote won't control the TV until you've programmed each button with a 5 digit EFC.  Let me know if you're interested in doing this and I'll convert the function numbers into the EFCs.
