White Balance Check Subject Clear chart (Color reproduction adjustment frame) Filter Filter C14 for color temperature correction ND filter 1.0 and 0.4 and 0.1 Measurement Point Video output terminal Measuring Instrument Vectorscope Specified Value Fig. 5-1-12. A to C Switch setting: 1) NIGHT SHOT OFF Checking method: 1) Check that the lens is not covered with either filter. 2) Select page: 6, address: 01, set data: 0F, and press the PAUSE button of the adjustment remote commander. 3) Check that the center of the white luminance point is within the circle shown Fig. 5-1-12. (A). 4) Select page: 6, address: 01, set data: 23, and press the PAUSE button. 5) Place the C14 filter on the lens. 6) Check that the center of the white luminance point settles in the circle shown Fig. 5-1-12. (B). 7) Remove the C14 filter, and place the ND filter 1.5 (1.0 + 0.4 + 0.1) on the lens. 8) Check that the white luminance point stopped moving, and then remove the ND filter 1.5. 9) Check that the center of the white luminance point settles within the circle shown Fig. 5-1-12. (C). Processing after Completing Adjustments: 1) Select page: 6, address: 01, set data: 00, and press the PAUSE button. R-Y 2mm B-Y 2mm Fig. 5-1-12. (A) R-Y 1.5mm B-Y 3mm 3mm Fig. 5-1-12.

Although this adjustment need not be performed when the circuit is damaged, etc., check the operations. • Note down the sensitivity displayed on the angular velocity sensor of the repair parts. At this time, note down also to which board it was attached to. Be sure to check because if attached incorrectly, the screen will vibrate up and down or left and right during hand-shake correction operations. Precautions on the Parts Replacement There are two types of repair parts. Type A: ENC03JA Type B: ENC03JB Replace the broken sensor with a same type sensor. If replace with other type parts, the image will vibrate up and down or left and right during hand-shake correction operations. After replacing, readjust according to the adjusting method after replacement. Precautions on Angular Velocity Sensor The sensor incorporates a precision oscillator. Handle it with care as if it dropped, the balance of the oscillator will be disrupted and operations will not be performed properly. Adjustment Page Adjustment Address F 41, 42 Note 1: The sensor sensitivity of SE451 and SE450 of the JK-170 board is written only on the repair parts. Adjusting method: 1) Select page: 0, address: 01, and set data: 01. 2) Read the sensor sensitivity written on SE451 (PITCH sensor) of the JK-170 board, and take this as S451. 3) Read the sensor sensitivity written on SE450 (YAW sensor) of the JK-170 board, and take this as S450. 4) Calculate D41' and D42' using the following equation (decimal calculation). NTSC model D41' = 92 / S451 D42' = 108 / S450 PAL model D41' = 148 / S451 D42' = 128 / S450 5) Convert D41' and D42' into hexadecimal digits, to obtain D41 and D42. (Round off decimal points) 6) Select page: F, address: 41, set data: D41, and press the PAUSE button of the adjustment remote commander. 7) Select page: F, address: 42, set data: D42, and press the PAUSE button of the adjustment remote commander. Processing after Completing Adjustments 1) Select page: 0, address: 01, and set data: 00. 2) Check that the steady shot operations have been performed normally. 3mm 3.5mm 1.5mm B-Y Fig. 5-1-12.
