How do I reset the Magnavox 20 inch TV Model 20MT1331/17 Smart Series made in 2005. I do not have the remote. There is no visible reset button. It is locked in to just four channels.

SOURCE: no remote, channels locked on smart tv

On this set, the volume buttons are the same as the menu button on your remote. The two channel buttons work the same as the scrolling arrows on your remote. It will take some practice, but to turn on the menu, press both volume buttons at once. Then practice using the volume controls to scroll. Once you have the hang of it, you can simply use these four buttons the same way you would have used your remote. If you cannot figure it out on your own, come back here, let me know, and I will sit down and map it out completely for you.

Hope this helps in some small way!
