2. DISASSEMBLY INSTRUCTIONS
Removal of mechanical parts and P.C. boards.
2.1 Back cabinet (refer to fig. 2.1)
a. Remove the screws which are used for holding the back cabinet to the front cabinet (6
screws for 14” models, 8 screws for 20” and 29” models).
b. Remove the screws which are used for holding the rear A/V input and output connectors.
c. Remove the back cabinet.
2.2 CRT PCB (refer to fig. 2.2/2.3)
CAUTION:
Before removing the anode cap, discharge electricity because it contains high
voltage. Before attempting to remove or repair any PCB, unplug the power cord from the AC
source.
a. Remove the anode cap.
b. Disconnect the ground connector (CM801).
c. Remove the CRT PC board.
2.3 Main PCB (refer to fig. 2.2/2.3)
a. Disconnect the following connectors: CM901, CM902, CM701, CM601, CM401 and
CM402
b. Unlock the PCB from the cabinet (both side of the board).
c. Remove the main PCB.
2.4 CRT (refer to fig. 2.4)
a. Remove the 4 screws.
b. Remove the CRT.
Note:
REMOVAL OF ANODE CAP – After turning the power off there might still be a
potential voltage that is very dangerous. When removing the ANODE CAP, make sure to
discharge the anode cap’s potential voltage. Do not use pliers to loosen or tighten the
anode cap terminal, this may cause the spring to be damaged.
