TV is on and just suddenly starts changing channels
When the above happens you cannot make it do anything with the remote or manually. We have unplugged it for a couple of hours and then it worked for awhile, but it starts right back doing the same old thing.

Re: TV is on and just suddenly starts changing channels
The switches in the front of the tv are usually the cause of this kind of problem. the fix is to replace all of the switches, because if 1 is bad the others are not far behind. each switch from rca is $5 to $10 each.

Try changing the input device to something you are sure, works such as a DVD player. Look for any loose contacts in RC jacks/sockets/Cable. Look for jammed buttons on remote and/or on control panel. Try removing the batteries from remote and operating from the control panel of TV. If these are ok, Switch off TV manually, switch off power, remove plug and retry after 48 hours. If problem persists, please refer it to a qualified service technician.
there may be a problem with the tvs remote sensor. most universal remotes you dont even have to enter any codes you just have to follow the same steps to enter the code but instead of entering a code all you have to do is press the channel up button after following all other steps, just keep pressing up until it turns the channel on the tv then press enter or similar button after it changes the channel and this should lock in the code without entering a specific code.And if all other remotes only half the buttons work on if it happens with every universal remotes then it probably a problem with the remote sensor or the tv . Good luck too ya!!!
Look in the owner's manual for instructions on having the TV scan channels. Make sure the converter is on before starting the scan. If that doesn't work, you'll have to buy or borrow a universal remote to take care of it (enter 3, 03 or 003 on the remote control). This will happen every time you remove power to the set, whether it is unplugged or you have a power failure, so start saving up for a new remote control.
hi do you mean the colour flashing on the screen, if so it's gone in to screen burn mode try press menu on the remote, retune the tv, if this don't work get back to me with model number of the tv help you a bit more thanks
"...it's possible that one of the front panel buttons is "stuck" or shorted, and this could cause the TV to ignore commands from the front panel or remote. But this should also cause the Power command to be ignored, too. You might try pulling off the front panel and disconnecting the front panel buttons and then see if the remote works."
