My neighbor was getting rid of a tv and I passed it on to a friend of mine. It is an RCA Model F27351WN. I brought it to the friends house and helped her hook it up. However, I'm unable to access the S-video inputs or even RCA red, white, yellow cables. There is no input select option on the tv's menu. I'm only able to access things input through the coaxial cable. We don't have the remote that came with the tv. Also, I set up the Comcast cable company's remote to use with the tv but the input select button doesn't change the inputs. It actually acts like a display button. Can someone help me figure out how I can access the S-video or RCA red, white, yellow cables? I would be very grateful. Thank you!
