SOURCE: tv channel problem
- I think you mean model P42. You can get the user manuals here:- http://www.vizio.com/support/downloads/ Note that the quickstart guide file is broken. You have to allow pop-ups, select the model and the manual will appear in a new window then you can save/print. Hope this helps! -

This likely has a bad main board.
I’m happy to help further over the phone at https://www.6ya.com/expert/dewayne_4a10eab6caecdb92
Check if the remote is in TV position, that is, because most of the remote controllers have the feature that you can program them for use with another devices. Make shure that one button that says "TV" in pressed and released once before you try to change any function on the TV.

In the menu, there should be an option for AUTO VOLUME, see what this is set at, change it and see if it works. Also there is another option for INTERNAL MUTE, though I still haven't found out what it's for, myself. Give both a go. If neither of these work, try looking at the support pages on the Samsung website. Other than that, I can only suggest you take it back to where you purchased it, and ask for an exchange.

The fault may be on the control board. Sometimes the button switches can be stuck, or there may be something causing some conduction on the control circuit board. It is also possible to have a component failure that is causing a continuous command to keep the volume to the high position.
Something that causes failures of controls in TV sets is when people clean the screen, they spray liquid cleaner on the screen. Some of it drips down in to the controls and on to the circuit board. This will usually cause damage, and thus the set will require shop service.
