If you have lost the remote control of your Insignia TV, you can still control it using the buttons on its case, voice commands, a smartphone app or a USB keyboard and mouse. Alternatively, you can buy a universal remote control or a streaming device whose remote can also be customized to control Insignia TV.
If your Insignia Fire TV remote does not work correctly, you need to reset it by pressing the "Back" button, the "Menu" button, and the "Left navigation" button simultaneously for 15-20 seconds.
In this article, I'll show you how to change the source on your Insignia TV without a remote. You can do this using the physical button on the TV itself or using the virtual remote on your smartphone.
