CHAPTER 1. GENERAL DESCRIPTION
[1] SAFETY PRECAUTION FOR SERVICE MANUAL
Precaution to be taken when replacing and servicing the Laser Pickup.
The AEL (Accessible Emission Level) of Laser Power Output for this model is specified to be lower than Class 1 Requirements. However, the follow­ing precautions must be observed during servicing to protect your eyes against exposure to the Laser beam.
1) When the cabinet has been removed, the power is turned on without a compact disc, and the Pickup is on a position outer than the lead-in posi­tion, the Laser will light for several seconds to detect a disc. Do not look into the Pickup Lens.
2) The Laser Power Output of the Pickup inside the unit and replacement service parts have already been adjusted prior to shipping.
3) No adjustment to the Laser Power should be attempted when replacing or servicing the Pickup.
4) Under no circumstances look directly into the Pickup Lens at any time.
5) CAUTION - Use of controls or adjustments, or performance of procedures other than those specified herein may result in hazardous radiation exposure.
[2] IMPORTANT SERVICE NOTES (FOR U.K. ONLY)
Before returning the unit to the customer after completion of a repair or adjustment it is necessary for the following withstand voltage test to be applied to ensure the unit is safe for the customer to use.

Since this DVD/CD system incorporates the following automatic adjustment functions, readjustment is not needed when replacing the pickup. Therefore, different PWBs and pickups can be com­bined freely.
Each time a disc is changed, these adjustments are performed automatically. Therefore, playback of each disc can be performed under optimum conditions.

[2] TEST MODE
The test mode applied to this microcomputer has three modes, namely the ordinary test mode for adjustment or measurement, the aging test mode, and the self-diagnosis test mode for self-judgment in case of final product inspection.
• The TUNER TEST 2 mode is obtained with >> + MEMORY/SET + ON/STAND-BY. ->Turn off AC in the TEST 2 mode to restore the initial state.
1. Turning on the test mode
For obtaining each test mode, press the ON/STAND BY button, while keeping pressing the following two buttons in the ordinary stand-by mode (power off). In this case, the main unit buttons are valid. When turning the POWER on with remote control buttons, test modes are not obtained.
[Ordinary test mode]
1. Tuner Test Mode (TEST 2)........................................................
TUNER(BAND) + DISC1
2. Electronic Volume Test Mode (TEST 3).....................................
TUNING DOWN + VOLUME UP
3. Timer Test Mode (TEST 4).......................................................

5. DVD MECHANISM Aging Test Mode (TEST 8).........................
DVD/CD + Equalizer
[Self-diagnosis Test Mode]
1. Button input diagnosis test mode (TEST 6)...............................
PRESET UP + DISC5
Processes are different depending on destinations at initial settings.
2. Tuner Test Mode (TEST 2)
1. Outline of tuner (radio) test mode
The tuner test mode is intended to store the adjustment and mea­surement frequencies in the preset memory CH. When adjusting the tuner section in the production line, adjusting personnel are not required to set frequency.
2. Details of tuner test mode
Press the "TUNER(BAND)" and "VOLUME UP" buttons in POWER OFF state and turn on the power by the use of "ON/STAND BY" button to preset and store frequency for adjustment and measure­ment of destination specified by the AREA terminal in the preset memory CH. However, Ordinary 1 and Ordinary 2 are stored in the destinations when the test mode is obtained.
(As for frequencies to be preset and stored for each destination, refer to item 3.)
The tuner test mode is started from preset No.1.
The operations of test mode are identical with the ordinary operations of TUNER function. FUNCTION switching is invalid.
It is necessary to discard the content of preset memory when the tuner test mode is ended; be sure to write "0000" or "1111" bits in the mem­ory to be checked for judging memory error at initial setting and to ini­tialize memory.
When the tuner test mode is obtained, the following display lights for one second.
Turn off POWER to protect the memory of TEST 2 mode.
Turn off POWER again to obtain the ordinary operation while the data is stored in the memory (besides TUNER).
If AC OFF state is maintained in this state for about 1/2 day, start is executed in the initial state.
• To clear the whole memory, insert the AC cord, pressing MEM­ORY/SET + PLAY.

3. Electronic volume Test Mode (TEST 3)
When this test mode is obtained, the following display lights for one second.
In this mode, volume is Volume -14 dB (STEP 23), FLAT AND X-BASS ON, and start-up function to DVD/CD, respectively. The button opera­tions in the test mode are the same as those of ordinary operation except volume UP/DOWN.
1) The display is the same as that of ordinary operation except test mode setting.
2) Unlike the ordinary state, the volume is controlled with the volume UP/DOWN button in accordance with the following three steps.
Vol ume - (STEP 0) <-> Volume-14 dB (STEP 23) <-> Volume-0 (STEP 30)
3) X-BASS is switched when button is pressed.
2 – 2
4. Timer test Mode (TEST 4)
When this test mode is obtained, the following display lights for one second.
Set the current time and timer time according to the following proce­dure to reproduce the timer.
1. Set the current time to 1:00, the timer to ON time 1:05, the function to DVD/CD, and volume to STEP 12, respectively. One minute is counted as one second, and the timer is reproduced. The fade-in (when playback is started) is executed at a rate of one step for 1 sec. After completion of fade-in, the fade-out is executed at a rate of one step for 1 sec (WAIT 1 sec inserted).
After completion of fade-out, the power is turned off (after WAIT 1 sec), and the mode is shifted to the standby.
The display during operation is the same as that of ordinary timer operation.
5. FL Test Mode (TEST 5)
When the FL test mode is obtained, all the FL segments are lighted. Then pressing the "PLAY" button switches display as below.
————–
Lighting of all segments
XL-DV50H
6. Button input diagnosis Test Mode (TEST 6)
When the test mode is obtained, the following is displayed.
(STAND-BY AND DEMO OFF STATUS)
This test mode is intended to check whether all the main unit buttons can be detected. Accordingly, in this test mode, it is checked whether the "ON/STAND BY" button was pressed after all the buttons shown below were pressed. If the result is OK, OK is displayed. If any one of keys was not pressed, an error is displayed. In both cases of OK termi­nation or error termination, the mode is shifted to the standby mode if the "ON/STAND BY" button is pressed subsequently.
All models using this type of microcomputer are not always provided with the same buttons. Since the buttons used are different depending on models, types of buttons to be used are determined by whether SURROUND, and an electric lid are available at the initial setting by MODEL port.
The order of buttons to be pressed is not determined. Accordingly, it is checked whether all buttons have been pressed.
1. PU-IN buttons: REW/PRESET DOWN + STOP
Since this model is provided with SURROUND (HAVE OR NOT), and electric DVD/CD lid, the following 10 buttons are detected as all buttons.
PLAY, X-BASS/DEMO, FUNCTION, VOLUME UP/DOWN, MEM­ORY/SET, REW, FF, STOP, DVD/CD-OPEN/CLOSE
The OK/ERROR display of test result is as follows.

CHAPTER 6. CIRCUIT SCHEMATICS AND PARTS LAYOUT
[1] NOTES ON SCHEMATIC DIAGRAM
XL-DV50H
•Resistor:
To differentiate the units of resistors, such symbol as K and M are used: the symbol K means 1000 ohm and the symbol M means 1000 kohm and the resistor without any symbol is ohm-type resis­tor. Besides, the one with “Fusible” is a fuse type.
• Capacitor:
To indicate the unit of capacitor, a symbol P is used: this symbol P means micro-micro-farad and the unit of the capacitor without such a symbol is microfarad. As to electrolytic capacitor, the expression “capacitance/withstand voltage” is used.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
(P.P.): Polypropylene type
• Schematic diagram and Wiring Side of P.W.Board for this model are subject to change for improvement without prior notice.

• The indicated voltage in each section is the one measured by Digi­tal Multimeter between such a section and the chassis with no sig­nal given.
1. In the tuner section,
( ) indicates AM
< > indicates FM stereo
2. In the main section, a tape is being played back.
3. In the deck section, a tape is being played back.
( ) indicates the record state.
4. In the power section, a tape is being played back.
5. In the CD section, the CD is stopped.
• Parts marked with “ ” ( ) are important for maintaining the safety of the set. Be sure to replace these parts with specified ones for maintaining the safety and performance of the set.
