Owner's manual gives instructions for activating the child lock feature - also possible to do so from the menu buttons on the front of the tv. Caught the Child Lock words on the screen as I was turning it off. Problem is - don't have the original remote, nor a universal one - we turned on/off and adjusted volume with the buttons on front of the set and used the Dish remote to change channels. Now I can't even get the tv to turn on manually. How do I get the TV on, to unprogram the child lock?
