If the TV is constantly changing the source, channel, or volume, there could be a problem with the remote control or touch panel on the TV.
Remove the batteries from your remote control.
To eliminate the possibility that the remote is sending commands to the TV, take the batteries out.
Unplug the TV.
With the TV powered on, unplug the TV from the wall outlet. If the TV has a one connect box, unplug it as well.
Clean the touch controls.
While the TV is unplugged, use a microfiber cloth to wipe down the touch controls on the bezel of the TV.
Plug the TV back in.
Plug the TV back in. Use the touch controls on the bezel to turn the TV back on. If the issue still occurs service is required.
Replace the batteries in the remote control.
Replace the batteries in the remote control with new ones and test functionality. If the abnormal behavior begins again there is a problem with your remote and it will need to be replaced. See our guide on replacing your remote control.
