Notes:
•
Only
new
circuits (circuits that are not published recently)
are described. For the other "known" circuits, see:
–
R8 manual.
–
FM24 manual.
•
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 block and circuit diagrams.
Where necessary, you will find a separate drawing for
clarification.

Introduction
The FTL13 is a 30-inch integrated LCD flat screen set, which
uses the (European) EM6 small signal panel (comparable with
R8 functionality). The HOP part is replaced by an Erasable
Programmable Logic Device (EPLD).
9.1.1
Features
This chassis has the following (new) features:
•
Next step "Active Control" with: two new bars ("Motion" and
"Tint Control" bar), four split demos, etc.
•
New LLC power supply, based on the one used in the
plasma monitors (FMxx chassis)
•
Small Signal Panel (SSP) that is based on the existing EM6
architecture: a full panel with integrated (shielded) Feature
Box as in the former MG-chassis. This approach gives
better EMC / crosstalk behavior and less cables.
•
Upgradeable main software (via ComPair).
9.1.2
Small Signal Panel
The SSP is a high tech module (four layer, 2 sides reflow
technology, full SMC) with very high component density and
partial shielding (FBX, EBILD) 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 is possible via ComPair.
Further features of the SSP are:
•
The 3D Comb filter functionality is integrated on the SSP.
•
The rear I/O connections are integrated on the SSP, even
as the tuner.
•
DVI input.
On the photographs you can see where all the functional cells
are located on the SSP:
