CDP-XE570 SECTION 1 SERVICING NOTE HOW TO OPEN THE DISC TRAY WHEN POWER SWITCH TURNS OFF Insert a tapering driver into the aperture of the unit bottom, and turn in the direction of arrow. Use a flat (–) head screwdriver to open the CD tray by manual operation. (Flat head screwdriver with nominal blade length of 3mm.) * To close the disc table, turn the driver in the reverse direction.
CDP-XE570 CD-TEXT TEST DISC This unit is able to display the TEXT data (character information) written in the CD on its fluorescent indicator tube. The CD-TEXT TEST DISC (TGCS-313: J-2501-126-A) is used for checking the display. To check, perform the following procedure. Procedure: 1. Turn ON the power and set the test disc. 2. Press the H button and play back the disc. 3. The following will be displayed on the fluorescent indicator tube. Display : 1kHz/0 dB/– – – – 4.

CDP-XE570 SECTION 3 DISASSEMBLY Note : Follow the disassembly procedure in the numerical order given. 3-1. LOADING PANEL • In order to remove the front panel block when the power supply does not turn on, rotate the cam with tapering driver as the figure shows, and the loading part will be moved. Then pull out the loading part by your hand to remove the loading panel as the figure shows. After that take out the front panel block. Loading panel Tapering driver Loading part 3-2.
CDP-XE570 SECTION 4 TEST MODE 4-1. CHECK MODE The following checks can be performed in the CHECK Mode. • Offset value display 1. Turn on the set. 2. Put disc in the set. 3. Press the [PLAY MODE] , H and M buttons simultaneously. 4. The Offset measured values will be displayed as “AB 02 FE” (typical values). • RFDC value display 1. Turn on the set. 2. Put disc in the set. 3. Press the [PLAY MODE], H and m buttons simultaneously. 4. The RFDC measured value will be displayed as “RFDC 65” (typical value).
CDP-XE570 4-3. ADJ MODE [ DISPLAY BOARD ] – Conductor side – The following operations are performed in the ADJ mode, which is set by connecting the TP1 (ADJ) terminal to the Ground and turning on the power.

CDP-XE570 SECTION 5 ELECTRICAL BLOCK CHECKING Note: 1. CD Block is basically designed to operate without adjustment. Therefore, check each item in order given. 2. Use PATD-012 disc (3-702-101-01) unless otherwise indicated. 3. Use an oscilloscope with more than 10MΩ impedance. 4. Clean the object lens by an applicator with neutral detergent when the signal level is low than specified value with the following checks. 1 track jump waveform Center of the waveform B A (DC voltage) 0V level : 1.15 ± 0.
