I have an old 2006 Philips tv that no longer has a remote. I have the silver Comcast remote with red ok button. Using the codes on Comcast's site, I'm able to control volume-only down though, increasing volume does not work with the remote, power, and menu button but ok/select does not work. Channel up/down does not work either, when I press it the cable button lights up. there is no cable hooked up to this tv, it is just for working out in the basement. I'd like to be able to use the remote to control content on a usb drive and a dvd player. The codes that I have used are 11454, 10054, 10690 and a bunch of others. Does anyone have a suggestion to get this to work?
