I have an RCA XL100 xs STEREO Commercial skip F19251GYTV. I no longer have the owners manual or remote for the TV. The remote is run through a Dish Network remote. I'm trying to find out how to get the TV to the AV setting. There is nothing in the Menu/Settings to switch nor is there a button or switch anywhere on the TV. Anyone no how to get it to AV? It must be there somewhere as the input/outputs are there. Thanks, JD
