oscilloscope (AC range) 2k â¦ IC501 @Â£ pin (RFO)
IC501 #Âº pin (VC)
1. Set the equipment to service mode stop state (See page 8). 2. Connect the oscilloscope between IC501 @Â£ pin (RF0) and #Âº pin (VC) on the MAIN board. 3. Move the optical pick-up by Pressing the + and = keys. 4. Put the disc (YEDS-18). 5. Press the ^ key. From focus searching, focus is turned ON while entering CLV drawing-in mode. Tracking and sled are turned OFF.
6. Press the PLAY MODE key. (Both tracking and sled are turned ON). 7. Check the oscilloscope waveform is as shown below. A good eye pattern means that the diamond shape (â) in the center of the waveform can be clearly distinguished.
RF level 0.85 â 1.15V
â¢ RF Signal Reference Waveform (eye pattern) To watch the eye pattern, set the oscilloscope to AC range and increase the vertical sensitivity of the oscilloscope for easy watching. 8. Stop removing of the motor by pressing the p key. 9. After the completion of adjustment, reset service mode. (See page 8 )
