@dicas.util5: We show you a hidden function of the USB port on old TVs from the 2000s to 2026 that almost no one knows about. We demonstrate how to connect your phone charger's USB cable to your TV's USB port, download the Infotec Tutorials app, and use it to transform your non-smart TV into a smart TV with new features and apps like YouTube. #OldTVHack #SmartTVTrick #HiddenFeature #TVUpdate #TechTutorial
