■ PREVENTION OF ELECTROSTATIC DISCHARGE

Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called

Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors and

semiconductor “chip” components. The following techniques should be used to help reduce the incidence of component damage caused by

electro static discharge (ESD).

1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any ESD on your body by

touching a known earth ground. Alternatively, obtain and wear a commercially available discharging ESD wrist strap, which should be

removed for potential shock reasons prior to applying power to the unit under test.

2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to

prevent electrostatic charge buildup or exposure of the assembly.

3. Use only a grounded-tip soldering iron to solder or unsolder ES devices.

4. Use only an anti-static solder removal device. Some solder removal devices not classified as “anti-static (ESD protected)” can generate

electrical charge sufficient to damage ES devices.

5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices.

6. Do not remove a replacement ES device from its protective package until immediately before you are ready to install it. (Most

replacement ES devices are packaged with leads electrically shorted together by conductive foam, aluminum foil or comparable

conductive material).

7. Immediately before removing the protective material from the leads of a replacement ES device, touch the protective material to the

chassis or circuit assembly into which the device will be installed.

CAUTION: Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.

8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing

together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity (ESD) sufficient to damage an

ES device).

Grounding for electrostatic breakdown prevention

1. Human body grounding:

Use an anti static wrist strap to discharge the static electricity

from your body.

2. Work table grounding:

Put a grounded conductive material (sheet) or iron sheet on

the area where the optical pickup is placed.

Caution:

The static electricity of your clothes will not be grounded

through the wrist strap. So take care not to let your clothes

touch the optical pickup.

Signal flow diagram of Mode 1

ACDR2 Check

By using the mode 1, mode 2 and mode 3 of the P.C.B.

test mode, the operation of the ACDR2 can be checked.

In Mode 1, the analog signal input/output operation is

checked.

In Mode 1, it is possible to check the A/D and D/A

converter function of CODEC, signal flow in ACDR2,

operation of the low pass filter in the input/output circuit.

In Mode 2, input of the optical digital signal and digital

output operation are checked.

The ADCR2 decodes the sub-code and displays the track

No. and the track time. To test this decoding function, the

digital output of the CD player is used.

In Mode 3, the digital coaxial signal input and analog

output operation are checked.

Starting the P.C.B. Test Mode

1) Turn off the power.

2) Remove the HDD unit for the convenience of the work

of the next step 3). (p. 14)

3) Short between pins No.1 and No.2 of the CB5. (MAIN

P.C.B., E3 in p.41)

4) Short between J909 and J913. (OSD P.C.B., C4 in

p.44)

5) Turn on the power.

6) The P.C.B. test mode is activated and “TEST mode

PCB” is displayed.

Mode 1 Operation Check

1) Set to Mode 1 by pressing the “

” key. “test
