SERVICE POSITION OF SERVO BOARD In servicing the SERVO board, erect the board as shown below. In this case, the CN201 and CN202 connectors are disconnected respectively, and accordingly the buttons on the front panel do not function. Therefore, use the Remote Commander for fundamental operations such as PLAY and STOP. Also, in performing the service under this condition, the stabilizer is not detected, so refer to “How to Operate the Set without Using Stabilizer”.
SECTION 3 DISASSEMBLY Note: Follow the disassembly procedure in the numerical order given. LOADING PANEL – BOTTOM VIEW – 2 tray 1 Open the tray turning the tapering screw driver to the arrow direction. 5 loading panel 3 two hexagon hole bolt (LID) 6 connector (CN292) 4 two screws...
SECTION 4 TEST MODE FLUORESCENT DISPLAY TUBE FULL ON AND – SERVO board (Conductor Side) – KEY CHECK MODE Procedure: 1. Connect TP(AFJ) and GND on the SERVO board with a lead wire. 2. Press button to turn the power ON. IC101 (AFJ) 3.

AGING MODE This set has the Aging mode for operation check of the mechanism deck. • If a failure occurred The aging operation stops and a faulty status is displayed on the fluorescent display tube. • If no failure occurs The aging operation continues repeatedly.
SECTION 5 ELECTRICAL ADJUSTMENTS Notes: RF signal waveform 1. CD block basically constructed to operate without adjustment. There- fore, check each item in order given. VOLT/DIV: 200 mV 2. Use YEDS-18 disc (Part No.: 3-702-101-01) unless otherwise indicated. TIME/DIV: 500 ns 3.

5. Confirm that the oscilloscope waveform is symmetrical on the top and bottom in relation to 0 Vdc, and check this level. Traverse waveform + 1.5 level: 1.5 Vp-p – 0.5 6. After check, remove the lead wire connected in step 1. Skew Adjustment Note: Do not perform the skew adjustment when not using attached sta- bilizer to a set.
