ASSEMBLY/CCD BOARD ASSEMBLY

1.6.1 Precautions

1.Take care in handling the CCD image sensor, optical LPF and lens components when performing maintenance etc., especially with regard to surface contamination, at- tached dust or scratching. If fingerprints are present on the surface they should be wiped away using either a silicon paper, clean chamois or the cleaning cloth.

2.The CCD image sensor may have been shipped with a protective sheet attached to the transmitting glass. When replacing the CCD image sensor, do not peel off this sheet from the new part until immediately before it is mounted in the OP Block Assembly.

3.The orientation of the optical LPF is an important factor for installation. If there is some marking on the LPF, be sure to note it down before removing and to reassem- ble it very carefully as it was referring to the marking.

1.6.2How to remove CCD board assembly and CCD base assembly

1.Unsolder the CCD board assembly by the 14 points (SD0) and then remove it.

2.Remove the two screws (1, 2) and remove the CCD base assembly.

Note0a: When removing the CCD base assembly, pay heed to the CCD image sensor because the spacer rubber and optical LPF are occasionally removed together with the CCD image sensor.

Note 0b: When replacing the CCD image sensor, don’t re- place it individually but replace the CCD base as- sembly in whole with a new one.

1.6.3How to assemble CCD base assembly and CCD board assembly

1.Install the optical LPF with the spacer rubber attached to its CCD side in the OP block assembly.

Note0c: Pay careful attention to the orientation of the LPF.

2.Set the CCD base assembly with careful attention to the spacer rubber not to come off the right position, and fas- ten them together with the two screws (1, 2).

3.Set the CCD board assembly in the CCD base assem- bly, and then solder it by the 14 points (SD0).

1.6.4 Replacement of service repair parts

The service repair parts for the OP Block Assembly are as listed below.

Before replacement of these parts, remove the bracket (OP assembly) as required.

Take special care not to disconnect any of the FPC wires or cause any damage due to soldering (excessive heating).

1.Focusing motor

2.Zoom motor

3.Iris motor unit

Note0d: When replacing the focusing motor or the zoom motor, solder the FPC at a space of about 1 mm above the terminal pin.

Note0e: The iris motor unit includes the FPC Assembly and two sensors.
