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 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. 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 WT540A. Follow 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 low-voltage 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 AC range are suitable. (See Fig. A)

HCD-GTR88 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.

UNLEADED SOLDER Boards requiring use of unleaded solder are printed with the leadfree mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size) : LEAD FREE MARK Unleaded solder has the following characteristics. · Unleaded solder melts at a temperature about 40 °C higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350 °C. Caution: The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful! · Strong viscosity Unleaded solder is more viscous (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc. · Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder. NOTE OF REPLACING THE IC102 ON THE DMB19 BOARD IC102 on the DMB19 board cannot exchange with single. When this part is damaged, exchange the entire mounted board. RELEASING THE DISC TRAY LOCK The disc tray lock function for the antitheft of an demonstration disc in the store is equipped. Releasing Procedure: 1. Press [I/1 STANDBY] button to turn the power on. 2. Press the [CD] button to select CD function. 3. While pressing the [x] button, press the [Z OPEN/CLOSE] button for more 5 seconds). 4. The message "UNLOCKED" is displayed and the disc tray is unlocked.
Note: When "LOCKED" is displayed, the slot lock is not released by turning power on/off with the [I/1 STANDBY] button.

This mode is use to load all the factory use preset frequencies into FM 1-FM 20 and AM 1-AM 10. Originally, frequency of FM 1-FM 20 and AM 1-AM10 are set to the minimum frequency. Procedure: 1. Press [?/1 STANDBY] button to turn on the system. 2. Press [EQ BAND/SURROUND], [x] button, and [DISC 1] button simultaneously and the message "FACTORY" appears on the fluorescent indicator tube. The function is changed to TUNER automatically.
CDM AGING MODE
This mode is used to display the total count of all disc playing. Procedure: 1. Press [?/1 STANDBY] button to turn on the system. 2. Select CD function and All DISC play mode. 3. Put discs on all trays and close the tray. 4. Press [GROOVE] button, [x] button and [RETURN] button simultaneously. 5. The fluorescent indicator tube displays Aging Display "AG xxxx/yyyy". "xxxx" represents the error counter (Maximum Value of "xxxx" = 9999) "yyyyy" represents the cycle counter (Maximum Value of "yyyy" = 9999) 6. Press [m/./TUNING ] or [M/>/TUNING +] to search for Aging History Error Display The fluorescent indicator tube displays "Mx E1E2E3E4". x: error history number E1: Loading sequence JCP high E2: Loading sequence JCP low E3: Loading operation JCP E4: Cam position operation JCP 7. Press [RETURN] to Aging Display · To release from CDM Aging Mode. To release from this mode, press [?/1 STANDBY] button or perform COLD RESET operation.
VACS DISPLAY
This mode is used to check the VACS level. Procedure: 1. Press [?/1 STANDBY] button to turn on the system. 2. Press [ERASE], [x] button and [ENTER] button simultaneously. 3. The fluorescent indicator tube displays "V0AP0". "V" represents Conventional VACS (Triggered by signal level) "AP" represents AP VACS (Abuse Protection Variable Attenuation Control System) · To release from VACS display mode To release from this mode, do the step (2) again.
METER SWITCH TOUCH COUNT DISPLAY
This mode is used to display the total count of meter pointer touch initial switch and max switch. Procedure: 1. Press [?/1 STANDBY] button to turn on the system. 2. Press [x] button, [ENTER] button and [DISPLAY] button simultaneously. 3. The fluorescent indicator tube displays "IxxxxxMyyyyy". "I" represents the Initial Switch touch. "xxxxx" represents the total count of Initial Switch touch. (Maximum Value of "xxxxx" = 65535) "M" represents the Max Switch touch. "yyyyy" represents the total count of Max Switch touch. (Maximum Value of "yyyyy" = 65535) · To release from Meter Switch Touch Count Display Mode. To release from this mode, do the step (2) again. The fluorescent indicator tube displays "MODE OUT".
