(29) Lens Frame, Lens Unit, Cushion and Crystal Filter
[DZ-MV780A]
1) Disconnect the flat cable.
2) Remove the screw [E].
3) Turn the GSL-M circuit board (e) up in the direction of the arrow.
4) Remove the two screws [F] and then remove the lens frame (a).
5) Remove the two screws [J], and then remove the lens unit (b), cushion (c) and crystal filter (d).
Note:
1) The lens unit and crystal filter are precision components: Take great care when handling them.
Adherence of any dust, foreign object, fingerprint, etc. to them, or any scratches or impact, could
cause a fault.
2) Never use metal tweezers to handle the crystal filter: Doing so could damage it.
Caution during disassembly and reassembly:
Take care with the orientation of crystal filter when assembling it: Incorrect orientation of the
crystal filter could cause a fault.
