HCD-GN90D/GN100D SECTION 1 SERVICING NOTES
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens. · MODEL IDENTIFICATION Back Panel
PART No.
LASER DIODE AND FOCUS SEARCH OPERATION CHECK Carry out the "S curve check" in "CD section adjustment" and check that the S curve waveform is output several times.

SECTION 4 TEST MODE
* Check of Amplifier 1. Press [EQ EDIT] button repeatedly until a message "GEQ MAX" appears on the fluorescent indicator tube. GEQ increases to its maximum. 2. Press [EQ EDIT] button repeatedly until a message "GEQ MIN" appears on the fluorescent indicator tube. GEQ increases to its minimum. 3. Press [EQ EDIT] button repeatedly until a message "GEQ FLAT" appears on the fluorescent indicator tube. GEQ set to flat. 4. When the [VOLUME] knob is turned clockwise even slightly, the sound volume increases to its maximum and a message "VOLUME MAX" appears on the fluorescent indicator tube. 5. When the [VOLUME] knob is turned counter-clockwise even slightly, the sound volume decreases to its minimum and a message "VOLUME MIN" appears on the fluorescent indicator tube. * Tape function 1. When a tape is inserted in Deck B and recording is started, the function is changed to VIDEO automatically. When [CD SYNC] button is pressed during recording in function, ALC (Automatic Logic Control) is turned on. 2. During recording, turn m M knob counterclockwise will stop the recording and the function is changed to TAPE B and rewind the tape in Deck B until the recording start position and playback of the tape B is started. If the [REC PAUSE/ START] button is pressed for a pause and pressed again to resume recording during recording time, when the tape is rewind, the tape will be rewind until the position where the pause is applied. * AMS Test Mode 1. Select the function "TAPE A" or "TAPE B". 2. Select Loop or Relay direction mode by pressing the [DIRECTION] button. Insert a test tape AMS-110A or AMS-120 to selected tape deck. 3. Press the [AMP MENU] button to enter the AMS test mode. 4. After the test tape is rewind to the beginning of the tape, the AMS+ is checked, and the mechanism is shut off after detecting the AMS signal twice. 5. Then the AMS- is checked and the mechanism is shut off after detecting the AMS signal twice. 6. When the check is complete, a message of either OK or NG appears on the fluorescent indicator tube. * To release from MC Test mode 1. To release from this mode, press ?/1 button. 2. The cold reset is enforced at the same time.
[GC TEST MODE]
· This mode is used to check the fluorescent indicator tube, LED, model, destination, software version, volume, key, jog, encoder and VACS level. Procedure: 1. Press x button, [ENTER] button and [DISC2] button simultaneously. 2. All LEDs and segments in fluorescent indicator tube are lighted up. 3. When you want to enter the software version display mode, press [DISC1] button. The model and destination are displayed. 4. Each time [DISC1] button is pressed, the display changes from MC version, GC version, CD version, ST version, TC version, TA version, TM version in this order, and returns to the MC version display. 5. When [DISC3] button is pressed while the version numbers are being displayed except model and destination, the date of the software creation appear. When [DISC3] button is pressed again, the display returns to the software version display. When [DISC1] button is pressed while the date of the software creation is being displayed, the date of the software creation is displayed in the same order of software version display. 6. Press [DISC2] button, the key check mode is activated. 7. In the key check mode, the fluorescent indicator tube displays "K0 J0 V0 E0". Each time a button is pressed, "K" value increases. However, once a button has been pressed, it is no longer taken into account. "J" value increases in the manner of 0,1, 2, 3 ... if [MULTI JOG] knob is turned clockwise, or it decreases in the manner of 0, 9, 8,7 ... if [MULTI JOG] knob is turned counter-clockwise.

Precaution 1. Clean the following parts with a denatured alcohol-moistened swab: record/playback heads pinch rollers erase head rubber belts capstan idlers 2. Demagnetize the record/playback head with a head demagnetizer. 3. Do not use a magnetized screwdriver for the adjustments. 4. After the adjustments, apply suitable locking compound to the parts adjusted. 5. The adjustments should be performed with the rated power supply voltage unless otherwise noted. Torque Measurement

1. Demagnetize the record/playback head with a head demagnetizer. 2. Do not use a magnetized screwdriver for the adjustments. 3. After the adjustments, apply suitable locking compound to the parts adjust. 4. The adjustments should be performed with the rated power supply voltage unless otherwise noted. 5. The adjustments should be performed in the order given in this service manual. (As a general rule, playback circuit adjustment should be completed before performing recording circuit adjustment.) 6. The adjustments should be performed for both L-CH and RCH. 7. Switches and controls should be set as follows unless otherwise specified. · Test Tape Tape P-4-A100 Signal 10 kHz, 10 dB Used for Azimuth Adjustment
