TV/Video on GE television

[shamgar03]

Alright well I have directv and a relatively old GE TV. The problem is I don't have the remote control to change the station to TV/Video. Does anyone know if there is a way to do this on the TV? Like by pushing two buttons at the same time. I can assure you there is no tv/video button on the box. Anyway any ideas would be helpful the model number is
25GT536

Edit: I think I could probobly get a universal remote, but I don't really want to spend much money, so links to cheap universal remotes would be nice.
