TV Sound Problem

I have a 13" Orion TV that I'd like to use for playing Halo with my buddies. Problem is that when I use headphones on it, I only get sound from one side. I can't find an option to change between mono and stereo or anything like that. Any help would be appreciated.

Buy? No, probably not. Make? Yes, after a fashion. You could quite easily make a short lead that connects the single audio output to both earpieces to give you dual mono, but that's not proper stereo. You won't get stereo sound out of a mono TV because the audio circuitry won't be designed to process stereo at all.
