Laser component in this product is capable of emitting radiation
exceeding the limit for Class 1.

This appliance is classified as
a CLASS 1 LASER product.
The CLASS 1 LASER PROD­UCT MARKING is located on
the rear exterior.

This caution
label is located
inside the unit.

SAFETY CHECK-OUT

After correcting the original service problem, perform the follow­ing safety checks 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

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 microampers). 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. 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 2V AC range are suitable. (See Fig. A)

Parts on Set

CAUTION

Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous ra­diation exposure.

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.

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.

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.

Data 0x9249, 0x2942, 0x4294 are written to the address
0x602 of RAM in the Servo DSP (IC701), then read and
checked.

(4-3) DSP Driver Test

Test signal data → DSP Driver
Error: Not detected.
Caution: Do not conduct this test with a mechanical deck
connected.
The maximum voltage is applied to the Servo Driver IC
(IC801, IC802). If mechanical deck is connected, the mo­tor and optics could be damaged. Disconnect mechanical
deck following the output message, then enter specified 4­or 5-digit number from the remote commander, and press
the [ENTER]. The test is conducted only when the input
data accord. Check the output level, then press the [NEXT]

of MB-82/85 board. Also, disconnect harness from the
CN011.

5. Supply

Caution: Do not conduct this check with a mechanical deck con-

nected.
An access is made to the stream supply and servo con­trol IC (IC303) and external RAM (IC304) using check
data. If mechanical deck is connected, the motor and
optics could be damaged. This check is also executed by
the “All” menu item.

Supplement: How to disconnect mechanical deck

Disconnect flat cables connected to the CN002 and
CN003 of DVD board. Also, disconnect harness from
the CN011.

(5-2) ARP Register Check

Data write → read, and accord check
Error 08: ARP register write, and read data discord
Data 0x00 to 0xFF are written to the TMAX register (ad­dress 0xC6) in ARP (IC303), then they are read and checked.

(5-3) ARP to RAM Data Bus

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 (IC304) connected to the
ARP (IC303) 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 (IC304) 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,

6. AV Decoder

(6-2) 1930 RAM

Data write → read, and accord check
Error 13: AVD RAM read data discord
The program code data stored in ROM (IC205) are copied
to all areas of RAM (IC402, IC403) connected to the AVD
(IC401) through the bus, then they are read and checked if
they accord. Further, 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, and read
data are displayed following the error code 13, and the test
is suspended.

(6-3) 1930 SP

ROM → AVD RAM → Video OUT
Error: Not detected.
The data including sub picture streams in ROM (IC205)
are transferred to the RAM (IC402, IC403) in AVD (IC401),

_

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 (IC304) connected to the ARP (IC303)
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,
and read data are displayed following the error code 11,
and the test is suspended.

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.
