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.x (development name “LC07”) is a new global chassis
for the year 2007 (LC7.1 is the analogue range, LC7.2 is the
digital range). It covers a screen size of 26 to 47 inch for LCD
and 42 to 50 inch for Plasma sets with a new styling called
“ME7”. Some key components are:
• Audio: Sound processing is performed by a multi-standard
sound processor MSP4450 (item 7411)
• Video: Video processing is performed by the Trident video
processor SVP CV32-LF (item 7202).
For analogue reception, a standard IF demodulator is used,
whereas digital input signals (DVB-T) are processed through a
COFDM channel decoder together with an MPEG decoder. A
so-called “Reneas” microprocessor performs the control
functionality.
Important features of this chassis are:
• AmbiLight: LED AmbiLight (where applicable) is
introduced as the successor of glass-tube AmbiLight
• 1080p Full HD (where applicable).
