2 = HDMI-2
3 = HDMI-3
4 = HDMI-4
ENT = Samsung TV on
. = Samsung TV off
Digital/Analog = Aspect

Tape Mode
1 = JVC Receiver off
2 = Samsung TV off
Rest = OSMC buttons

Component Select
A = TV, ENT, TV, 1, AMP, 8, SAT (TV)
B = TV, ENT, TV, 3, AMP, 9, TAPE (OSMC)
C = TV, ENT, TV, 3, AMP, 1, CD (WDTV)
D = TV, ENT, TV, 3, AMP, 0, DVD, Play (DVD)

To reset a component select: Press and hold Set and then hold D until the light goes off.
To learn a component select: Press and hold Set, and then D, let go of both. The light will stay on.
