To engineers in charge of repair or inspection of our products.

Before repair or inspection, make sure to follow the instructions so that customers and Engineers in charge of repair or inspection can avoid suffering any risk or injury.

1. Use specified parts. The system uses parts with special safety features against fire and voltage. Use only parts with equivalent characteristics when replacing them. The use of unspecified parts shall be regarded as remodeling for which we shall not be liable. The onus of product liability (PL) shall not be our responsibility in cases where an accident or failure is as a result of unspecified parts being used.

2. Place the parts and wiring back in their original positions after replacement or re-wiring.

For proper circuit construction, use of insulation tubes, bonding,gaps to PWB, etc, is involved. The wiring connection and routing to the PWB are specially planned using clamps to keep away from heated and high voltage parts. Ensure that they are placed back in their original positions after repair or inspection. If extended damage is caused due to negligence during repair, the legal responsibility shall be with the repairing company.

3. Check for safety after repair. Check that the screws, parts and wires are put back securely in their original position after repair. Ensure for safety reasons there is no possibility of secondary ploblems around the repaired spots. If extended damage is caused due to negligence of repair, the legal responsibility shall be with the repairing company.

4. Caution in removal and making wiring connection to the parts for the automobile. Disconnect the battery terminal after turning the ignition key off. If wrong wiring connections are made with the battery connected, a short circuit and/or fire may occur. If extensive damage is caused due to negligence of repair, the legal responsibility shall be with the repairing company.

5. Cautions regarding chips. Do not reuse removed chips even when no abnormality is observed in their appearance. Always replace them with new ones. (The chip parts include resistors, capacitors, diodes, transistors, etc). The negative pole of tantalum capacitors is highly susceptible to heat, so use special care when replacing them and check the operation afterwards.

6. Cautions in handling flexible PWB Before working with a soldering iron, make sure that the iron tip temperature is around 270 ply the iron tip repeatedly(more than three times)to the same patterns. Also take care not to apply the tip with force.

7. Turn the unit OFF during disassembly and parts replacement. Recheck all work before you apply power to the unit.

ERROR 6

Note:

1. For the DVD changer,refer to the service manual provided with the DVD changer.

2. If an error display other than the ones described above appears, press the reset button.

3. When the reset button is pressed,frequencies of TV/radio stations,titles,etc. stored in the memory are cleared.

Cause A CD inside the CD changer is not loaded. A CD inside the CD changer cannot be played due to scratches,etc. A CD inside the CD changer cannot be played because it is loaded upside-down. Displayed when the temperature in the MD changer is too high and playback has been stopped automatically. An MD inside the MD changer is not loaded. An MD inside the MD changer cannot be played due to scratches,etc. A MD inside the MD changer cannot be played because it is loaded upside-down. Displayed when a non-recorded MD is loaded in the MD changer.

- 2 -VRX630

Measure This is a failure of CD changer's mechanism. Replace with a non-scratched,non-warped disc. Eject the disc then reload it properly.

Lower the surrounding temperature and wait for a while to cool off MD changer. This is a failure of MD changer's mechanism. Replace with a non-scratched,non-warped disc. Eject the disc then reload it properly.

Load a pre-recorded MD in the MD changer.

TROUBLESHOOTING

Problem Nothing happens when buttons are pressd. Display is not accurate.

Cause The microprocessor has malfunction due to noise,etc.

Measure Turn off the power,then press the RELEASE lever and remove the DCP.Press the Reset button for about 2 seconds with a thin rod.

Reset button

CLOCK ADJUSTMENT

1. Press the ADJ button to display the adjustment selection display.

2. Move the JOYSTICK up or down to select CLOCK,then press ENT at the center of the JOYSTICK to display the clock adjustment display.

3. Move the JOYSTICK left or right to select HR or MIN,then move the JOYSTICK up or down to adjust the time.

※The time is displayed in 12-hour format.

4. Pressing ENT at the center of the JOYSTICK when the cursor is above HR or MIN saves the adjusted value in memory and simultaneously returns the display to the previous display(adjustment selection display). To cancel clock adjustment before completion,use the JOYSTICK to move the cursor to MENU,then press ENT at the center of the JOYSTICK.

ADJUSTMENTS

Dot clock adjustment(at Digital PWB)

1. Turn the screen on,and connect TP601(TEST) to GND.

Input the visual signal(10step wave,monochrome,APL=50%,

1.0Vp-p)to the VIDEO input.

10step wave

1. BRIGHT voltage confirmation(NTSC mode) Make sure the voltage of TP706 is 1.88+0.1/-0.1V.

2. RGB-AMP/CONT-G adjustment(NTSC mode) Adjust VR707(RBG AMP) so that VBB voltage of TP710

VOLTS/DIV=0.1V(10:1PROVE)

A.B TIME/DIV=10usec.

GND

Fig.1

is 4.0+0.5/-0.5V. Adjust VR703(CONT) so that VBW voltage of TP710 is

3.8+0.05/-0.05V.

3. BRT-R Adjustment(NTSC mode) Adjust VR705(BRT-R) so that VBB voltage of TP711 is

4.0+0.05/-0.05V.

4. BRT-B Adjustment(NTSC mode) Adjust VR706(BRT-B) so that VBB voltage of TP709 is

4.0+0.05/-0.05V.

5. COM-AMP adjustment(NTSC mode) Adjust VR704(COM-AMP) so that the amplitude of TP705 is 6.7+0.1/-0.1Vp-p.
