ATTENTION AU COMPOSANT AYANT RAPPORT
À LA SÉCURITÉ!
LES COMPOSANTS IDENTIFIÉS P AR UNE MARQUE ! SUR LES DIAGRAMMES SCHÉMATIQUES ET LA LISTE DES PIÈCES SONT CRITIQUES POUR LA SÉCURITÉ DE FONCTIONNEMENT. NE REMPLACER CES COM­POSANTS QUE PAR DES PIÈCES SONY DONT LES NUMÉROS SONT DONNÉS DANS CE MANUEL OU DANS LES SUPPLÉMENTS PUBLIÉS PAR SONY.
SAFETY CHECK-OUT
After correcting the original service problem, perform the follow­ing safety check before releasing the set to the customer: Check the antenna terminals, metal trim, “metallized” knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microamperes). Leakage current can be measured by any one of three methods.
1. A commercial leakage tester , such as the Simpson 229 or RCA WT -540A. Follo w the manufacturers’ instructions to use these instruments.
2. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The “limit” indica­tion is 0.75 V, so analog meters must have an accurate low­voltage scale. The Simpson 250 and Sanwa SH-63Trd are ex­amples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2 V A C range are suit­able. (See Fig. A)
To Exposed Metal Parts on Set
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 pick-up block. Therefore, when checking the laser diode emis­sion, observe from more than 30 cm away from the objective lens.
LASER DIODE AND FOCUS SEARCH OPERATION CHECK
Carry out the “S curve check” in “CD section adjustment” and check that the S curve waveforms is output three times.
Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam­aged by heat.

Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270 ˚C dur­ing repairing.
• Do not touch the soldering iron on the same conductor of the circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering or unsoldering.
CAUTION
Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous ra­diation exposure.

CD-TEXT TEST DISC
This unit is able to display the TEXT data (character information) written in the CD on its fluorescent indicator tube. The CD-TEXT TEST DISC (TGCS-313:J-2501-126-A) is used for checking the display. To check, perform the following procedure.
Checking Method:
1. Turn ON the power, set the disc on the disc table with the side labeled as “test disc” as the right side, close the front cover, and chuck the disc.
2. The following will be displayed on the fluorescent indicator tube. (The display switches each time the [TIME/TEXT] button is pressed.)
Display: CD TEXT TEST DISC (Album Title)
3. Press the [] button and play back the disc.
4. The following will be displayed on the fluorescent indicator tube. (If nothing is displayed, press the [TIME/TEXT] button.)
5. Rotate [AMS] knob to switch the track. The text data of each track will be displayed. For details of the displayed contents for each track, refer to “Table 1: CD-TEXT TEST DISC Text Data Contents” and “Table 2: CD­TEXT TEST DISC Recorded Contents and Display”.
Restrictions in CD-TEXT Display
In this unit, some special characters will not be displayed properly. These will be displayed as a space or a character resembling it. For details, refer to “Table 2: CD-TEXT DISC Recorded Contents and Display”.

ALL ERASE
This mode is used for clearing information such as the title memo. Do not execute if information such as the title memo is not to be erased.
Procedure:
While pressing the [CLEAR] button with the power OFF, press the 1/u button and turn on the power.
[]
The fluorescent indicator tube displays “ALL ERASE” and all memories will be cleared.
AGING MODE
• Mode which repeatedly changes and plays back discs automati­cally in the unit.
• It will repeat aging as long as no errors occur.
• If an error occurs during aging, it will stop all servos, motors, etc. instantaneously, display the error number, and stop opera­tions. However, the stopping conditions differ according to whether the unit is equipped with the “self-protection function during errors” described later. The function serves to maintain the state of the unit when errors occur.

Special Aging Mode Functions
e
The aging mode is provided with the following convenient func­tions
• Disc setting mode (*1)
• Selection of presence of protection function during error (*2)
• Count function of aging cycle (*3)
*1 Disc setting mode:
5 discs are set before setting the aging mode. This mode makes the setting of these discs more easy.
*2 Self protection function during errors:
Function which voluntarily corrects errors which occur dur­ing normal operations by retries. If this function is not provided, all operations will be stopped without retiring. It is suitable for checking errors with low re­producibility . If this function is provided, and errors can be corrected by retries, aging will be continued without stopping.
*3 Aging cycle count function:
Functions which displays the number of agings carried out on the Fluorescent indicator tube in numbers. One aging cycle consists of five discs.

Aging Procedure
1. Turn ON the power of the unit. Press the [OPEN/CLOSE]
§
and open the front cover.
2. Change the [COMMANDMODE] switch (S901) on set to [CD1].
3. Press the [AGINGSTART] button of the remote commander for aging mode (J-2501-123-A).
4. When the disc set mode is set, the [] and [] LEDs blink.

5. Rotate the [DISC/CHARACTER] dial. The slits (No. 60, 120, 180, 240, 300) for setting the discs will come forward. Insert the discs into these slits. Do not set the discs in other slits.
6. Set whether the self-protection function during errors is equipped with the unit. Press the [REPEAT] button. If “RE- PEA T” is displayed on the fluorescent indicator tube, it means the function is provided. If “REPEAT” is not displayed, it means the function is not provided.

TEST MODE

5-1. ADJ MODE
1. Turn ON the power of the unit, set disc to disc table, and per­form chucking.
2. Remove the power cord from the outlet.
3. To set ADJ mode, connect the pin of IC501 (ADJ) of the MAIN board to ground, and connect the power cord to the outlet.
In this mode, table rotation and loading operations are not per­formed because it is taken that the disc has already been chucked.
Note: The same operations are also performed in the following when the
pin of IC501 (ADJ) is connected to ground after turning on the power.
• Direct search (movement of sledding motor) is not performed during accessing
• Ignored even when GFS becomes L
• Ignored even when the Q data cannot be read

ELECTRICAL ADJUSTMENT

1. CD Block is basically designed to operate without adjustment. Therefore, check each item in order given.
2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated.
3. Use an oscilloscope with more than 10 M impedance.
4. Clean the object lens by an applicator with neutral detergent when the signal level is low than specified value with the fol­lowing checks.
S-Curve Check

Procedure :
1. Chuck the disc (YEDS-18) beforehand, and remove the power cord from the outlet.
2. Connect oscilloscope to test point TP (FE1) on BD board.
3. Connect pin of IC501 (ADJ) on MAIN board to ground with lead wire.
4. The ADJ mode is set when the power cord is inserted into the outlet and power is supplied.
5. The fifth track is played automatically.
6. Press the [CHECK] button.
7. Check the oscilloscope waveform (S-curve) is symmetrical between A and B. And confirm peak to peak level within 3±1 Vp-p.

9. After check, disconnect the lead wire connected in step 3.
Note : • Try to measure several times to make sure than the ratio of A :
B or B : A is more than 10 : 7.
• Take sweep time as long as possible and light up the brightness to obtain best waveform.
Note: A clear RF signal waveform means that the shape “” can be clearly
distinguished at the center of the waveform.
