If you have Cox Cable, the information below, from another user is correct. I tried "0030" on the Cox Cable remote, and it now controls my Trutech 15" TV/DVD player.



For Trutech tv owners try the codes under Goldstar tv brand. Or such other brands as , AOC, Candle, Envision, Kenwood, Nec. In UEI made remotes, its code 0030.
