If you do not have a colour analyser

, you can use the default

values. This is the next best solution. The default values are
average values coming from production.
•

Select a COLOUR TEMPERATURE (e.g. COOL,
NORMAL, or WARM).

•

Set the RED, GREEN and BLUE default values according
to the values in

Table 6-4

and

Table 6-5

•

When finished press OK on the RC, then press STORE (in
the SAM root menu) to store the aligned values to the NVM.

•

Restore the initial picture settings after the alignments.

Alignment of the Ambilight modules

Every Ambilight module is aligned by a matrix and by the
brightness. After replacement of a module, the brightness must
be aligned with the other modules.

Method:

Go to SAM (press OK button).

Select “Alignments”.

Select “Ambilight”: a white testpattern shall be displayed.

Select the number of the module (pixel) that has to be
aligned. Module 1 is the first one which will come across
according the wire connections starting by the small signal
panel and proceding towards the ambient light
modules.The first module will be attached to the next
module 2, module number 2 to number 3 etc.

Align the brightness compared with the neighbouring
modules. The brightness will be automatically stored.

Select one of the 10 matrixes which color corresponds with
the neighbouring modules. “Matrix 0” is the factory
alignment and can always be retrieved. The alignment is
stored automatically.

6.3.3

TCON/VCOM alignment

Sets with forward integration have the TCON on SSB. The
alignment of this TCON is stored in the SSB, and is related to
the used display. When an SSB or a display is replaced, a new
value must be entered.
A default value (see table below) is copied from the display file
(after entering the correct display code) and is shown in the
SAM menu. But on top of this, the default value can be
overruled manually via the menu item “TCON alignment”.
The current value is shown with 4 digits, and can be changed
by a digit entry. After pressing “OK”, the value is stored.
The menu item "Reset TCON alignment" can be used to return
to the default value from the display file. A notification is shown:
"TCON alignment has been reset".

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
PNX51XX 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,
