Introduction Firmware updates are released by companies after the device hits the market to resolve software problems and add new features to those devices; in the case of Insignia TV's, it's the latter. If your Insignia TV is running fine, there's no need to update the firmware, even if an upgrade is available. However, if you're experiencing software problems, such as the TV randomly turns itself on and off or if the TV's settings aren't working as they should, Insignia may have released a firmware update that resolves that problem. Insignia TV firmware updates are free and don't take more than half an hour to install, including the time it takes to download the file and place it on a USB flash drive.
