Try an autoscan & see if it picks it up. If that doesnt work a factory reset will do the job.
I cant give you the freq for that channel as I`m in Ireland.
FACTORY RESET
Menu > system set up and then go to Factory reset and press OK to reset,
Installation, choose your provider and then Auto Scan, when its finished scanning and found the channels, press exit.
Menu > 1570
Set Default Key > OK
Turn Key Code On
Exit back to channels & you`re sorted.
