[For Dz-Hs303A/Gx3300A]; Ccd Image Sensor And Gsl-3M Circuit Board [For Dz-Hs303A/Gx3300A] - Hitachi DZ-HS303A Service Manual

Disassembly and Reassembly > Disassembly
(23) Lens Frame, Lens Unit, Cushion and Crystal Filter
1) Disconnect the fl at cable.
2) Remove the screw [C].
3) Turn the GSL-3M circuit board (e) up in the
direction of the arrow.
4) Remove the two screws [D].
5) Remove the screw [C] and then remove the
lens frame (a).
6) Remove the two screws [F] and then remove
the cushion (c) and the crystal fi lter (d) from
the lens unit (b).
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.
(24) CCD Image Sensor and GSL-3M Circuit Board
1) Unsolder the 26 points at the CCD image
sensor (a) terminal on GSL-3M 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.
