remove module.
(5) Detach ribbon cable connectors P1011 (W1) and P4012 (W4) from mating connectors
J5011 and J5012 on solder side of low voltage power supply module and remove the
module.
NOTE:
For further disassembly of LVPS module, refer to Figure 6-15 .
E. High Voltage Power Supply Assembly Removal
(1) Disconnect high-voltage lead (W11) from cathode-ray tube (73).
