Main system control memory IC fault. This is a very small IC; have 8 solder terminals, and can be located very near to the main system control-chroma IC. Check and replace it. Be sure to replace it with the same number printed on it; in all respect. Otherwise, it won't go. http://electronicshelponline.blogspot.com/

Is it the tv's remote? Change the batteries
are you on a cable box? You need to use the providers channel changer. Tv is made to stay on one channel like channel 3 and the cable box runs the different channels.

This is a fairly common issue. First remove the batteries from your remote control/s that are capable of operating your tv. Did this stop the issue? If so, you need to replace your batteries, if not, check the remotes for ay stuck buttons or the possibility of them having had any liquid spilled on them since the problem started. If all is still negative, how close do you live to your nearest neighbor? Sometimes people who live in apartments will receive the input of a remote control from a person living next to them. If all else has been checked, and you have ruled any of your neighbors, then I'm afraid to tell you that the electronics which control the channel and volume settings on your tv are in the process of going bad. This is most likely caused by a small capacitor, but once the capacitor has gone, it can cause even more components to receive incorrect voltages and in turn ruin them causing cascade electronic failure. A repair shop can fix or replace the components or the board, But cost wise, it is rarely worth doing so.

Try a re-tune. Refer its user manual for details.

The first thing to try is to see if a button is stuck on the remote or on the TV.
Remove the batteries on the remote and see if that helps. If it fixes the problem, you'll need to replace the remote.
If that doesn't help, look close at the buttons on the TV to see if one is jammed on. If changing channels continually up, then check the channel up button on the TV, if down then check the down button.
Worst case, you might have to take the back off the TV and unplug the cable feeding the external button panel on the TV and only use the Remote (for safety, rememeber to unplug the TV while doing any work on it).

Look at the input or video select button. Change it once and attempt to change channels, if the problem persists continue to change the input selection until you can select channels.
THANK YOU AND PLEASE RETURN FOR ADDITIONAL HELP IF NEED BE.

Pull out the power plug of your TV and don't use it for few minutes. Remove batteries from your remote and keep it without batteries for few minutes. After about 15 minutes your TV and remove both will work fine.

Ii would begin by changing the batteries in the remote. As they lose their power they will control some functions but not others. If that doesn't solve it, get back and we can take additional steps. i want to help.

Remove batteries from remote, and test again the touch buttons on TV with remote batteries out. This to exclude the possibility that remote has a stuck button.

If the problem persists , then it is probably a faulty IR board on TV (the one that gets IR signal from remote), or a faulty touch button switch.
