Your symptoms point to the main board [the board with all the input connections], no simple fix, you must replace the board. Less likely the keypad is bad, just unplug the keypad and see if channel display stops popping up.

Tune the tv to a channel that is just blue screen. Then turn the tv off and unplug for at least 30 sec. Then plug the tv back in and turn it on. Then leave the tv on the blank screen channel go into the menu and do auto cable channel search. After the search is complete try all channels. This worked for me. My tv will not scan if the tv is on a channel that comes in. GOOD LUCK these tv's are junk .

Child lock on tv


All you have to do is turn the TV on and turn to a channel that doesn't prompt the V-chip password (even if it's snowy) and hold down the volume (down -) button on the main unit while holding down the number "0" on the remote control. It might take a few tries, and you might need to change the TV channel for some reason but if done correctly, either the TV will turn off, or the menu screen will pop up and ask if you want to set the vchip password, either way you should be able to watch your TV now! :)
