Sherwood LCD: LF-401-TB5, NEC NLT40/46FHD100

(Also sold as Grundig). This follows LG codes, but uses a Samsung LCD panel.)

The following table shows the mapping of T460 channel number, the string sent, and the input associated with that channel in

the manual, and how it is identified on the on-screen menu. It has a “set ID” field in commands (the “00” in messages below),

which seems to default to 01 in the set. However, messages with an ID = 00 are acted on by all connected panels.
