Notes:
•
Only new circuits (circuits that are not published recently)
are described.
•
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 (chapter 6) and
Circuit Diagrams (chapter 7). Where necessary, you will
find a separate drawing for clarification.
9.1
Introduction
The LC7.5x chassis (development name “LC07S”) is a digital
derivative from the digital LC7.2x chassis (development name
“LC07”). It covers screen sizes of 32" and 42" with a new styling
called “SuperNova” and 52" with existing styling “ME7”.
Some delta’s with respect to the LC7.2x chassis are:
•
Video: Video processing is performed by the Trident video
processor SVP WX86 (item 7C01) which outputs a signal
of 1080p (no additional 1080p panel needed), introduces
Digital Natural Motion (DNM) and supports MPEG Artifact
Reduction.
•
AmbiLight: FPGA-based AmbiLight controller integrated on
SSB (no additional AmbiLight panel needed).
•
Audio: introducing BBE
®
technology for increased speech
intelligibility and music performance with an additional
subwoofer.
•
HDMI: Additional HDMI connector with on-board switch
has been added.
•
On-board DC-DC converters: DC-DC-converters on-
board the SSB have been changed.
For (other) features of the chassis, please refer to the
LC7.2E LA Service Manual.
