Channel changing automatically and TV remote not working

two choices, get the keyboard on the set repaired or get an original sharp remote which among remotes is not too expensive.

You will need to complete a channel scan from the tvs menu. I assume you have basic cable and that your cable company is still providing analog channels for you to be able to pick up any transmission on this telvision with the digital changeover and all.

Usually if you go into the setup menu, there is an option to allow you to either "scan" for a channel, or "input" a channel. In this case, select "input" and see if the TV will allow you to press the up and down channel buttons and go to a specific channel. If so, when you get to channel 4, press the "add this channel" option (or whatever the menu option says) and you should then be able to go to channel 4 using the buttons on the front without skipping over it.

most likely buttons on front panel are going bad.

Go into your menu. Sounds like your Parental lock might be "on". You should be able to solve your problem in the menu. Keever

I personally would get myself a "Universal Remote". These units will operate almost ANY unit that uses Infrared... Ya Punch a "Code" in for your particular TV etc, and thats it... total conrtol...

1 either your remote button has pressed or some dust in contact. 2 dust near front panel buttons. 3 problem in sytem control section. 4 memory ic .

You must program the tv. Go into the MENU and find AUTO PROGRAM. Then program it and it should work.
