Tv won't turn on like it's unplugged but it's not

It seems that the set itself changes inputs. Place it remote control away from the vicinity of the tV. and check. If it does the same, do a hard reset next. To make it a hard reset, unplug the TV from AC mains wall socket, and replug it back after 10 minutes or so. If these do not help you, be sure that the main system control memory IC to it is faulty and should be replaced.

On and off commands come from the main board, if it won't shut off you need a new board

It seems to be a common misconception that the remote is necessary to turn a device on. All devices have hard-wired power controls. Does THAT work? It is unclear which device (remote or the Cinemate) is malfunctioning. If the Cinemate won't turn on by its own power switch the remote won't magically bypass whatever the problem is.

The Cinemate Manual offers some steps to take if it won't turn on, as well as other guidance.
