home entertainment device does not respond.
SOLUTION: Make sure the remote control is aimed at your home
entertainment device and is not farther than 15 feet away.
PROBLEM: CH! and CH"do not work for your RCA TV.
SOLUTION: Due to RCA design (1983-1987), only the original remote

Theater mode, does not display a secondary menu screen.
SOLUTION: Even though SCROLL is displayed, for these modes, there are
no additional menu screens.
