Possible Solution(s)
If the channel lineup is locked (recommended setting), only
channels that are active in the TV's channel lineup can be
selected. Set 028 CH. OVERIDE to 1 to allow access for direct
keypad entry to all channels.
Channel access is restricted to channels included in the FTG
Channel Map. If necessary, make changes to the FTG Channel
Map using the FTG File Manager.
Refer to Express Script or Custom Master TV Setup procedure,
as appropriate. Auto Tuning must be run in order for the channel
lineup to be populated. Note for Express Script: You must select
"Execute Auto Search" in the Auto Search screen to run search
(see page 15). To reactivate the Express Script, perform an
"IN-STOP" to restore factory defaults on the TV.

dealer, as necessary. Then, check settings both in the TV and on
the remote. IR codes sent by the remote must match the
setting(s) in the TV.
