Will this tv need a digital converter box if we

If you are refering to signal you receceive on an antenna, then yes. It's actually called a Digital Tuner. The standard analog tuners that are in most older TV's will work for the Analog signals that you will probibally still be receiving, the Digital signals will not be available to you. This will depend on if stations in your area are at transmitting in Digital or analog or both. These boxes are the devices the government was either giving away, or making availalbe for a low cost to those whom need it via cupons. This has ended, but you can check this gov site out that talks in detail about it. You can buy the Digital Tuner boxes for pretty cheap from what I havce seen, but you will probibally need an antenna also.
