Where Fire TVs have a sleek service menu, Panasonic's smart TVs have one that looks straight out of the early 2000s. As soon as you turn on your Panasonic TV, press the Volume Down button and hold it.

Here's a lifehack for your smart TV: use this button combo to activate a secret menu that can do some cool stuff.

To view this menu, press and hold the Action button on your remote for a second, then press down on the Directional ring. After 3-4 seconds, release both buttons and press the Menu button.
