My t.v is on video input and i need to change it

on the front panel of the tv should be a menu button where you can then changes various settings of the tv.

I had the same problem and had to order a replacement remote off eBay. There are plenty of them on there. The one you want for your TV is: SANYO T.V. REMOTE CONTROL Model FXWC. Search for that and you'll find what you need. Mine cost $15.00 including shipping. There appears to be no other way to do what you are trying to do.

Good luck!
