Very much appreciate your response. My tv is a Sylvania 27 inch model # SRT2227X. There is no "source" button on either the remote or the tv. The closest I come up with is the menu button which wasn't helpful. What's my next move? Thanks again.
ok, according to the manual for your TV, you have RCA inputs on both the front and back of the TV. Connect to whichever set you want, and to cycle to that input source, select the "game" button on the remote.
for future reference, here is a .pdf of your TV's manual http://www.manualshark.org/manualshark/files/21/pdf_14912.pdf
hope that helps!
