Note: Pin
3, 4 of CN1611 are open.
Procedure:
1. Connect a digital voltmeter to the CN1561 (CN1611, CN1761, CN1861).
2. Press the [POWER] button to turn on the main power.
3. Adjust the RV1501 (RV1551, RV1601, RV1701, RV1751, RV1801, RV1851) so that the digital voltmeter reading is 5 mV to 20 mV.
1. Connect a digital voltmeter to the CN1561 (CN1611, CN1761, CN1861).
2. Press the [POWER] button to turn on the main power.
3. Adjust the RV1501 (RV1551, RV1601, RV1701, RV1751, RV1801, RV1851) so that the digital voltmeter reading is 5 mV to 20 mV.
Note: Adjust for the digital voltmeter reading to become 5 mV as much as possible.

VIDEO CALIBRATION ADJUSTMENT
Adjustment to decide the standard of the video input signal.
Note: After replacing D VIDEO board, or after “SUPER RESET” of the
special menu mode is executed, perform this adjustment.
1. Adjustment jig
The color pattern generator that can output 100% in NTSC/PAL/
HD color bar signal to the component and the composite at the
same time is necessary for the adjustment.
When there is no color pattern generator, it is possible to substitute
it by the Blu-ray Disc player that can output the component termi-
nal and the video terminal at the same time (Substitution model
name example: BDP-S350).
However, please do the following signal output confi rmation with
the oscilloscope beforehand when substituting it with the Blu-ray
Disc player.
