Customer Question

I have a 2003 apex television model #at2704s that I accidentally locked the controls to.
Neither the remote nor the manual controls are working. Also, at the bottom of the screen
a red key insignia appeared. What do I need to do to unlock the controls?

Press the function, or F, and the mute button at the same time and hold, for ten seconds and that should take care of your problem.
