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.
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 leaka ge 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 A C milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a V OM
or battery-operated A C 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 A C range are suitable. (See Fig. A)
CAUTION
Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation exposure.
This appliance is
classified as a CLASS 1
LASER product. This
label is located on the
rear exterior.
The following caution label is located inside the
apparatus.

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 objecti ve lens.

Data write → read, and accord check
Error 09: ARP ↔ RAM data bus error
Data 0x0001 to 0x8000 where one bit each is set to 1 are
written to the address 0 of RAM (IC303) connected to the
ARP (IC302) through the bus, then they are read and
checked. In case of discord, written bit pattern and read
data are displayed. If data where multiple bits are 1 are
read, the bits concerned may touch each other. Further, if
data where certain bit is always 1 or 0 regardless of written
data, the line could be disconnected or shorted.
(5-4) ARP to RAM Address Bus
Data write → other address read discord check
Error 10: ARP ↔ RAM address bus error
Caution: Address and data display in case of an error is
different from the display of other diagnosis (de-
scribed later).
Before starting the test, all addresses of RAM (IC303) are
cleared to 0x0000. First, 0xA55A is written to the address
0x00000, and the address data are read and checked from
addresses 0x00001 to 0x80000 while shifting 1 bit each.
Next, the data at that address is cleared, and it is written to
the address 0x00001, and read and checked in the same
manner. This check is repeated up to the address 0x80000
while shifting the address data by 1 bit each. If data other
than 0 is read at the addresses except written address, an
error is given because all addresses were already cleared to
0. In this check, the error display pattern is different from
that of other diagnosis; read data, written address, and read
address are displayed in this order. However, the message
uses same template, and accordingly exchange Address and
Data when reading. The following display, for example,
### Syscon Diagnosis ###

shows the data 0xA55A was read from address 0x00080000
though it was written to the address 0x00000000. This implies that these addresses are in the form of shadow. Also,
if the read data is not 0xA55A, another error will be present.
(5-5) ARP RAM Check
Data write → read, and accord check
Error 11: ARP RAM read data discord
The program code data stored in ROM are copied to all
areas of RAM (IC303) connected to the ARP (IC302)
through the bus, then they are read and checked if they accord. If the detail check was selected initially, the data are
written to all areas and read, then the same test is conducted
once again with the data where all bits are inverted between
1 and 0. If discord is detected, faulty address, written data,

This screen displays current servo adjusted data stored in the
EEPROM. Though adjusted data can be initialized with the
[CLEAR] key on the remote commander, they cannot be restored
after initialization. So, before clearing, make a note of the adjusted
data. For reference, the drive has been designed so that the gain
center value is 20 and offset value is 80. Other values will be in a
range of 10 to 80. If extreme value such as 00 or FF is set, adjustment
will be faulty. In such a case, check for disc scratch or cable
disconnection, then perform adjustment again.
