Cautions when disassembling or re-assembling the projector
The Keypad board is installed on the Upper case. When removing, lift carefully without excessive force to
prevent damaging cables and connectors.
When removing the Drive board, there might be damage to the flexible cables of LCD panels and two board-
to-board connectors. Handle them with care when disassembling.
(1) Before remove the Drive board, disconnect the all cables from connectors on it.
(2) Lift up the Drive board straightly to disconnect two board-to-board connectors on the opposite side of it,
after taking off the screws of it.
(3) When you remove/install the PWB assembly Drive from/to the unit, make sure that the IR sensor on the
Drive board stands vertically.
The fan cooling sirocco fan is easily damaged; therefore, use care to avoid applying any impact after
removing the optical unit.
