Product Specifications
The basic chassis comes with NICAM and fast text as standard and can drive CRT’s from 56 to 76cm in both 4:3
and 16:9 formats. The only 4:3 sets that use this chassis are the 59ESD7H and 66ESD7H, both of which are
Dolby Pro-Logic models.
All variants of this chassis are fitted with three SCART sockets on the rear of the board – composite video, S-
Video and RGB can be fed into these sockets. In addition to this, some models have front AV sockets (phono and
S-Video).
All Dolby Pro-Logic models have full functionality, allowing connection of separate speakers for front left, front
right, rear left, rear right and sub-woofer. In the Pro-logic mode (once correctly set up in the user menu) the
internal speakers – left, right and centre - become the centre channel.

In some FW and GF models, and in all HW models, an earth plane was added to the top surface of the PWB
(double copper), this is green in colour. This reduces interference and the possible corruption of the NVM
caused by power supply variations and CRT discharges. It is possible to identify these chassis as the fourth digit
of the serial number starts with the number 5.
In later FW sets, a power factor module was fitted as a separate PWB. This was connected between the output
of the mains bridge rectifier and the main smoothing block. Its function is to ensure that the current/voltage
draw from the mains is kept in sync. This eliminates ‘spikes’ or ‘troughs’ in the mains voltage waveform which
keeps the electricity suppliers happy.
Note that the first three digits before the serial number are in fact the month and year of manufacture, i.e.
201
512112 is January 2002.
