Is my Sony Trinitron Television Model KV-27FS100L 2006 digital?

If you mean to ask if your TV contains a digital tuner, the answer is no. Your TV only contains an NTSC tuner. If you are using an antenna connection, you will need to also connect a tuner (digital converter).

In the future, I recommend that you do not post your serial number publicly. This is specific to your TV and should not be shared. The model number was enough information to get specifications.
