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- (see chapter
9. Block Diagrams
) and circuit diagrams (see chapter
10. Circuit Diagrams and PWB Layouts
).Where necessary,
you will find a separate drawing for clarification.
7.1 Introduction
• implementation of “passive” 3D
• removal of TCON from the SSB (comes with the display)
• changed power architecture
The LE63x chassis uses the PNX855xx chipset. The major
deltas S551 are:
•support of DVB-T2 (“second generation” DVBT).
