FOCUS BIAS CHECK
1. Connect the oscilloscope to TP (RF) and TP (GND) on the CD board. 2. Insert the disc (YEDS-18). (Part No. : 3-702-101-01) 3. Press the u (CD) button. 4. Confirm that the oscilloscope waveform is as shown in the figure below. (eye pattern) A good eye pattern means that the diamond shape (�) in the center of the waveform can be clearly distinguished. � RF signal reference waveform (eye pattern)

T1 AM IF Adjustment
1. Set to power off state. 2. Connect a digital voltmeter to TP (DIMMER) and TP (GND) on the LCD board and confirm that the voltage is 0 V. 3. Turn on the power. 4. Connect the digital voltmeter to TP (DIMMER) and TP (GND) on the LCD board and adjust RV401 so that the voltage becomes 1.5 ± 0.05 V. 5. Turn off the power. 6. Applied sufficient light to IC403 (brightness sensor) on the DIMMER board and confirm that the voltage is 3.3 ± 0.3 V. 7. Short the BP404. Adjustment Location: � LCD BOARD (Component Side) �
