9.1 X Board
9.1.1 Purpose
Receiving LOGIC signal from the CONTROL board and make
ADDRESS PULSE (generates Address discharge) by ON/OFF
operation, and then supplies this waveform to TCP (data).
Figure 9-1 X boards
9.1.2 Dismantling
1. Remove connections between the boards:
Figure 9-2 Between CONTROL board and X board
1. Lift up lock as indicated by the arrows (handle with care, as
this part is easy to break).
2. Pull TCP as indicated (handle with care, as the TCP film
part is easy to damage).

9.2 Z Sustain Board
9.2.1 Purpose
To make the SUSTAIN and ERASE pulses that generates
SUSTAIN discharge in the panel by receiving LOGIC signal
from
CONTROL board. This waveform is then supplied to the panel
through FPC (Z).
