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; only applicable in some 
regions) 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).
