Sanyo TV Won't Switch to TV VIDEO mode?

[???~~]

So, my boyfriend accidentally hit the channel buttons, and that caused our TV to go into that mode. Well, we can't get it to go back to TV/VIDEO mode. We don't have a remote control for it, and have tried a universal; it doesn't work. Does anyone know how to get it to go into TV/VIDEO mode? It's a Sanyo DS31590
