Lens Unit, Cushion And Crystal Filter [For Dz-Gx3200A]; Ccd Image Sensor And Gsl-2M Circuit Board [For Dz-Gx3200A] - Hitachi DZ-HS303A Service Manual

Disassembly and Reassembly > Disassembly
(25) Lens Unit, Cushion and Crystal Filter
1) Disconnect the fl at cable.
2) Remove the screw [C].
3) Turn the GSL-2M circuit board (d) up in the direction of the arrow.
4) Remove the two screws [F].
5) Remove the two screws [D] and then remove the cushion (b) and the crystal fi lter (c) from the
lens unit (a).
Note:
1) The lens unit and crystal fi lter are precision components: Take great care when handling them.
Adherence of any dust, foreign object, fi ngerprint, etc. to them, or any scratches or impact, could
cause a fault.
2) Never use metal tweezers to handle the crystal fi lter: Doing so could damage it.
Cautions during disassembly and reassembly:
Take care with the orientation of crystal fi lter when assembling it: Incorrect orientation of the
crystal fi lter could cause a fault.

(26) CCD Image Sensor and GSL-2M
Circuit Board
[For DZ-GX3200A]
1) Unsolder the 14 points at the CCD image
sensor (a) terminal on GSL-2M circuit board
(b).
Note:
The CCD image sensor is a precision component:
Take great care when handling it.Adherence of
any dust, foreign object, fi ngerprint, etc. to it,or
any scratches or impact, could cause a fault.
