Note:
• Only new (not recently published) circuits are described
ere. For the other circuit descriptions, see a.o. the FTL13
Service Manual.
• In the following text, the model year 2003 refers to the
FTL13 chassis, while the model year 2004 refers to the
new FTL2.1 chassis.
• Figures can deviate slightly from the actual situation, due
to different set executions.
• For a good understanding of the following circuit
descriptions, please use the wiring, block and circuit
diagrams. Where necessary, you will find a separate
drawing for clarification.
9.1 Introduction
This chassis contains, compared to its predecessor, the
following new features/components:
• New Small Signal Board (SSB) with lower height due to
a.o. flat mounted tuners. This board is completely shielded
(i.s.o. only the FBX).
• FEM (Falconic Embedded Memories): this is a new
Falconic IC with internal Field memories and jagged line
removal feature.
• Improved 2D/3D Comb filter: The new key components
are Columbus and SDRAM. When SDRAM is used, a 3D
comb filter (or temporal comb filtering) is possible. Without
SDRAM, only 2D comb filtering (or spatial comb filtering) is
possible. This is improved with respect to the previous 2D
comb filter.
• Improved noise reduction: This is a second function of
the Columbus and SDRAM. Noise reduction is possible
without SDRAM (2D) and with SDRAM (3D).
• Pixel Plus 2: Eagle 1B is replaced by Eagle 1C.
– Algorithms for Horizontal LTI and Vertical LTI are
improved.
– "Thin Line Control" as part of the sharpness control.
– "Face Depending Peaking" should allow less
sharpness in faces different from the rest of the picture.
This could be used to anti age faces versus the rest of
the picture.
– "Vivid Colors 1" will result in more saturated colors.
– The range/amount of "Blue Stretch" is extended.
– More steps of "Green Enhancement".
– Improved "Color Dependent Sharpness".
– Increased range of skin gain and skin tone.
• Proximity sensor: to detect motion when the customer is
approaching the set, and then to light up the LEDs on the
set for 6 s (detection area is 1.5 - 2 m).
• Improved/new AutoTV functions: AutoTV 2004 has
some new hardware configurations. Applying an LCD
panel requires to have contrast reserve and backlight
regulation. Applying a PDP panel requires having contrast
reserve as well (no backlight regulation). The Eagle 1C is
detected automatically. “Columbus improved noise
reduction” is used when the Columbus is present.
• Ambient Light: To control lamps at the rear of the TV with
respect to the measured ambient light level from the light
sensor or the picture content, a control output from AutoTV
has been foreseen.
• DVI input for Europe, HDMI input for NAFTA and AP.
The chassis consists of a full sized SSB, a Power Supply, and
some smaller PWBs for Audio, I/O, and Control functions. The
main functionalities are:
• Power Supply:
– For FHP displays, this is an LLC power supply, based
on the one used in the earlier plasma monitors (FMxx
chassis). This supply (single sided) is built up very
conventional, with hardly any surface mounted
components on the copper side.
– For SDI displays, this is a "black box" for Service
(board/module swap).
• SSB: Core TV functionalities, being TXT(CC)/control,
video and audio decoding, feature box, video featuring,
and sync/geometry control. The SSB is a high tech module
(four layer, 2 sides reflow technology, full SMC) with very
high component density and full shielding for EMC-
reasons. Despite this, it is designed in such a way, that
repair on component level is possible. To achieve this,
attention was paid to:
– Clearance around surface mounted ICs (for replacing).
– Detailed diagnostics and fault finding is possible via
ComPair.
– Software upgrading (only for main software) is possible
via ComPair.
On the drawings (next page), it is indicated where all the
functional cells are located on the SSB (mind you that this is
just an indication):
