When service is required, the original lead routing and dress should be observed, and it should be confirmed that they have been returned to normal, after re-assembling.
5. Leakage currnet check (Electrical shock hazard testing) After re-assembling the product, always perform an isolation check on the exposed metal parts of the product (antenna terminals, knobs, metal cabinet, screw heads, headphone jack, control shafts, etc.) to be sure the product is safe to operate without danger of electrical shock. Do not use a line isolation transformer during this check.
Plug the AC line cord directly into the AC outlet. Using a "Leakage Current Tester", measure the leakage current from each exposed metal parts of the cabinet, particularly any exposed metal part having a return path to the chassis, to a known good earth ground. Any leakage current must not exceed 0.5mA AC (r.m.s.).
Alternate check method Plug the AC line cord directly into the AC outlet. Use an AC voltmeter having, 1,000 ohms per volt or more sensitivity in the following manner. Connect a 1,500 10W resistor paralleled by a 0.15 F AC-type capacitor between an exposed metal part and a known good earth ground. Measure the AC voltage across the resistor with the AC voltmeter. Move the resistor connection to each exposed metal part, particularly any exposed metal part having a return path to the chassis, and meausre the AC voltage across the resistor. Now, reverse the plug in the AC outlet and repeat each measurement. Voltage measured any must not exceed 0.75 V AC (r.m.s.). This corresponds to 0.5 mA AC (r.m.s.).

Preventing static electricity
MX-K50R
1. Grounding to prevent damage by static electricity
Electrostatic discharge (ESD), which occurs when static electricity stored in the body, fabric, etc. is discharged, can destroy the laser diode in the traverse unit (optical pickup). Take care to prevent this when performing repairs.
2. About the earth processing for the destruction prevention by static electricity
In the equipment which uses optical pick-up (laser diode), optical pick-up is destroyed by the static electricity of the work environment. Be careful to use proper grounding in the area where repairs are being performed.
2-1 Ground the workbench
Ground the workbench by laying conductive material (such as a conductive sheet) or an iron plate over it before placing the traverse unit (optical pickup) on it.
2-2 Ground yourself
Use an anti-static wrist strap to release any static electricity built up in your body.
(caption) Anti-static wrist strap
Conductive material (conductive sheet) or iron plate
3. Handling the optical pickup
1. In order to maintain quality during transport and before installation, both sides of the laser diode on the replacement optical pickup are shorted. After replacement, return the shorted parts to their original condition. (Refer to the text.)
2. Do not use a tester to check the condition of the laser diode in the optical pickup. The tester's internal power source can easily destroy the laser diode.
4. Handling the traverse unit (optical pickup)
1. Do not subject the traverse unit (optical pickup) to strong shocks, as it is a sensitive, complex unit.
2. Cut off the shorted part of the flexible cable using nippers, etc. after replacing the optical pickup. For specific details, refer to the replacement procedure in the text. Remove the anti-static pin when replacing the traverse unit. Be careful not to take too long a time when attaching it to the connector.
3. Handle the flexible cable carefully as it may break when subjected to strong force.
4. It is not possible to adjust the semi-fixed resistor that adjusts the laser power. Do not turn it
Attention when CD mechanism assembly is decomposed
*Please refer to "Disassembly method" in the text for pick-up and how to detach the CD mechanism assembly.
1. Remove the CD changer unit.
2. Remove the CD changer mechanism.
3. Solder is put up before the card wire is removed from the pickup unit connector on the CD mechanism assembly. (When the card wire is removed without putting up solder, the CD pick-up assembly might destroy.)
4. Please remove solder after connecting the card wire with the pickup unit connector when you install picking up in the substrate.

Maintenance of laser pickup
(1) Cleaning the pick up lens Before you replace the pick up, please try to clean the lens with a alcohol soaked cotton swab.
(3) Semi-fixed resistor on the APC PC board
The semi-fixed resistor on the APC printed circuit board which is attached to the pickup is used to adjust the laser power. Since this adjustment should be performed to match the characteristics of the whole optical block, do not touch the semi-fixed resistor. If the laser power is lower than the specified value, the laser diode is almost worn out, and the laser pickup should be replaced. If the semi-fixed resistor is adjusted while the pickup is functioning normally, the laser pickup may be damaged due to excessive current.
(2) Life of the laser diode When the life of the laser diode has expired, the following symptoms will appear.
1. The level of RF output (EFM output : amplitude of eye pattern) will below.
Is the level of
RF OUT under
1.1V 0.2Vp-p?
YES
O.K
NO
Replace it.
Replacement of laser pickup
Turn off the power switch and,disconnect the power cord from the ac outlet.
Replace the pickup with a normal one.(Refer to "Pickup Removal" on the previous page)
Plug the power cord in,and turn the power on. At this time,check that the laser emits for about 3seconds and the objective lens moves up and down. Note: Do not observe the laser beam directly.
Play a disc.

Functions
Crystal resonator connection (4.5MHz/7.2MHz)
Serial data input : FMIN is selected when DVS is set to 1. The input frequency range is from 10 to 160MHz. The signal is passed through a built-in divide-by-two prescaler and then supplied to the swallow counter. A1 though the range of divisor setting is from 272 to 65, 535, the actual divisor is twice the setting since there is also a built-in divide-by-two prescaler.
Serial data input : AMIN is selected when DVS is set to 0. Serial data input : When SNS is set to 1 : The input frequency range is form 2 to 40MHz The signal is supplied directly to the swallow counter. The range of divisor setting is from 272 to 65, 535 and the actual divisor will be the value set. Serial data input : When SNS is set to 0 : The input frequency ranges is from 0.5 to 10MHz. The signal is supplied directly to a 12-bit programmable divider. The range of divisor setting is from 4 to 4,095 and the actual divisor will be the value set.

Functions
Used as the synchronization clock when serial data is input to the LC72131 (DI ), or when serial data is output (DO).
Inputs serial data sent from the controller to the LC72131M.
Output serial data sent from the LC72131M to the controller. The content of the output data is determined by the serial data DOCO to DOC2.
The LC72131M power supply (VDD=4.5 to 5/5V) The power on reset circuit operates when power is first applied.
The LC72131M ground.
Dedicated output pins The output states are determined by BO1 to BO4 in the serial data. 'Data"=0:Open =1:Low The pins go to the open state after the power-on reset. An 8Hz time base signal can be output from BO1 when TBC in the serial data is set to 1. Note that the ON impedance of the BO1 pin is higher than that of the other pins (BO2 to BO4)

Pins used for both input and output The input or output state is determined by bits IOC1 and IOC2 in the serial state. 'Data"=0:Input port =1:Output port When specified for use as an input port : The input state is transmitted to the controller through the DO pin. 'Input state"=Low:data value 0 =High:data value 1 When specified for use as an output port : The output state is determined by bits IO1 and IO2 in the serial sate. 'Data"=0:Open =1:Low These pins go to the input port state after the power-on reset.
PLL Charge pump output When the frequency generated by dividing the Local oscillator frequency by N is higher than the reference frequency, a high level will be output from the PD in. similarly, when that frequency is lower, a low level will be output. The PD pin goes to the high impedance state when the frequencies agree.

IF counter
The input frequency range is from 0.4 to 12MHz. The signal is supplied directly to the IF counter. The result from the IF counter MBS is output through the DO pin. There are four measurement periods: 4, 8, 32 or 64ms.
