9.1 Introduction
The LC7.xH (development name “LC07”) is a new iTV chassis
for the year 2007 (LC7.1 is the analogue range, LC7.2 is the
digital range). It is the successor of the LC4.xH chassis, and
covers a screen size of 26 to 42 inch for LCD, with a new styling
called “ME7”.
The LC7.1HE LA chassis is derived from the LC7.1E LA
chassis: it uses an analogue only derived SSB from this
chassis, and an i-Board (and in some models an integrated
card slot) for iTV functionality. The iTV specific board (i-Board)
and the integrated card slot in this chassis are for Service a
“black box”, and therefore must be replaced completely when
defective (board swap).
