(21) GYR-H Circuit Board, Lens Frame, Lens Unit, Cushion, Crystal Filter, CCD Image
Sensor, and SEN-H Circuit Board in VDR-M70
GYR-H Circuit Board (a)
1) Remove two screws [D], and then remove the GYR-H circuit board.
Lens Frame (b)
2) Remove one screw [D].
3) Release the two tabs.
4) Remove the lens frame in the direction of the arrow.
Lens Unit (c), Cushion (d) and Crystal Filter (e)
5) Remove two screws [L], and then remove the lens unit, cushion and crystal filter.
CCD Image Sensor (f) and SEN-H Circuit Board (g)
6) Unsolder the fourteen points of CCD image sensor terminals on SEN-H circuit board.
Note:
1) The lens unit, crystal filter and CCD image sensor are precision components: Take great care
when handling them. Adherence of dust, foreign object, fingerprint, etc. to them, scratches or
impact, could cause a fault.
2) Never use metal tweezers to handle the crystal filter: Doing so could cause a fault.
Procedure and caution for reassembly
1) Take care with the orientation of crystal filter when assembling it: Incorrect orientation of the
crystal filter could cause a fault.
2) When assembling the lens unit into lens frame, insert the flat cable (h) of lens unit inside the lens
frame.
