After installing a new Sony Trinitron TV set and connecting the device to an antenna, you will need to tune the set before you can view all available digital-television stations. Tuning an existing Sony Trinitron TV set will update the channel line-up with any changes as old stations stop broadcasting or change frequency and new stations come on-air. Sony Trinitron sets include an automatic tuning feature that you can access from the remote control handset to scan for channels and add them to the TV’s integrated electronic program guide.
