CD-MD3000H/CD-MD3000W NOTES ON SCHEMATIC DIAGRAM • 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 pico-farad and the unit of the capacitor without such a symbol is microfarad.

CD-MD3000H/CD-MD3000W TROUBLESHOOTING CD SECTION When the CD does not function When the CD section does not operate when the objective lens of the optical pickup is dirty, this section may not operate. Clean the objective lens, and check the playback operation. When this section does not operate even after the above step is taken, check the following items. Remove the cabinet and follow the troubleshooting instructions.
PAGE 89
CD-MD3000H/CD-MD3000W Check in the CD test mode. STEP 1 Does the display "E-CD01" appear? Yes No Does the pickup move to the inner/outer position using the 'UP'/'DOWN' key? Check the line of PU-IN SW. Check from pin 2 of CNP6 via pin 25 of CNP1 to pin 94 of IC901. No Check the line of the slide control. Check from pins 3 and 4 of CNP6 via pins 17, 18 and 22 of IC5 to pin 40 of IC2. No Check from pins 7 and 8 of CNP5 via Q4 and pins 6 and 7 of IC6 to pin 38 of IC2.
PAGE 90
CD-MD3000H/CD-MD3000W MD SECTION When MD fails to operate If the objective lens of optical pickup is contaminated, MD may fail to operate. At first, clean the objective lens to check playback operation. If MD fails persistently to operate, perform checks as follows. If dust or foreign substance is accumulated on the pickup lens, playback is disturbed and indication of TOC (content of tracks) may be disabled. Before adjusting check that the lens is clean. If the lens is contaminated, treat it as follows.

CD-MD3000H/CD-MD3000W • Disc loading is not normal. Is disc loaded when it is inserted? Yes No Is +5V to +6V applied to the pins 17 and 18 of CN1501? No Check the power PWB, Main PWB, and CN1501. Yes Is pulse input in the pin 6 of CN1501 when reset power supply is turned on? Check the Main PWB and CN1501. No Yes Is +3.2V applied to the pin 62 of IC1401? No Check the periphery of Q1804 and IC1401. Yes Check IC1201. Is pulse of 8.4672MHz applied to the pin 15 of IC1401? No Yes Check IC1401.
PAGE 92
CD-MD3000H/CD-MD3000W • Normal playback When it has been confirmed that EEPROM value is normal in the TEST mode Is initialization performed normally when high reflection disc is played back? Does the playback time display advance? Yes No No Check IC1201.
PAGE 93
CD-MD3000H/CD-MD3000W • The spindle motor does not rotate. Is waveform output from the pins 24 and 25 of IC1201 in the step 4 of AUTO auxiliary adjustment mode of TEST mode? No Check the pins 24 and 25 of IC1201, soldering of peripheral circuit, and parts. Yes Is waveform output from the pins 9 and 10 of IC1601 and the pins 5 and 6 of CN1402? No Check IC1601, CN1402, and soldering of mechanism switch PWB. Yes Replace with a spindle motor (complete). • The sled motor does not rotate.
