9.1
Introduction
The ES1E is a flat screen type CRT TV set for the year 2005 -
2006. It is based on the SSB of the A02, but the LSP, called
Esplanade, has been redesigned in order to reduce the "hot"
part of the chassis. In this chapter, only the deflection circuits,
the correction circuits and the X-ray protection circuits are
described.
9.1.1
Large Signal Panel
The Esplanade chassis has a full sized LSP, which is has been
redesigned with respect to the previous A02 chassis in order to
reduce the "hot" parts of the circuit.
The main functionalities of the LSP are:
•
Supply,
•
Deflection,
•
Sound amplification.
The LSP (single sided) is built up very conventional, with hardly
any surface mounted components on the copper side.
