@dicas.util5: We show you a hidden feature that's been on TV USB ports since 2005 that most people don't know about. We plug a USB cable from a phone into the TV's USB port, visit Infotec Tutorials, and follow simple steps to transform an old TV into a fully functional Smart TV with apps like YouTube, without needing to buy a new TV or expensive box devices. #SmartTV #USBPort #TechHack #OldTV #DIY
