Introduction
The microprocessor communicates with a large number of I
ICs in the set. To ensure good communication and to make
digital diagnosis possible, the microprocessor has to know
which ICs to address. The presence / absence of these
MT5366 ICs (back-end advanced video picture improvement
IC which offers motion estimation and compensation features
(commercially called HDNM) plus integrated Ambilight control)
is made known by the option codes.
Notes:
After changing the option(s), save them by pressing the OK
button on the RC before the cursor is moved to the left,
select STORE and press OK on the RC.
The new option setting is only active after the TV is
switched "off" / "stand-by" and "on" again with the mains
switch (the NVM is then read again).
