MD-MX30/MX30W 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 micro-micro-farad and the unit of the capacitor without such a symbol is microfarad.

MD-MX30/MX30W TROUBLE SHOOTING 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.

Check the peripheral circuits at pins 18 and 19 on IC1, pin 23 on IC2, and Bi2. Yes "IL" is possible, but play is not possible. No Yes No "IL" is not possible. A normal jump operation cannot be completed or the beginning of the track cannot be found. Check the around pin 23 on IC2. Data cannot be read.

MD-MX30/MX30W 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.

MD-MX30/MX30W • Disc loading is not normal. Yes Is disc loaded when it is inserted? No Is +5V to +6V applied to the pins 17 and 18 of CN1501? No Check the power supply PWB, system PWB, and CN1501. Yes Is pulse input in the pin 6 of CN1501 when reset power supply is turned on? Check the system PWB and CN1501. No Yes Is +3.2V applied to the pin 62 of IC1401? No Check the periphery of Q1804 and IC1401. Yes Is pulse of 8.4672MHz applied to the pin 15 of IC1401? Check IC1201.
PAGE 74
MD-MX30/MX30W • 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. Does disc rotate normally? Yes No Is lead-in switch turned on in the TEST mode when the pickup is on the innermost periphery? (Is the pin 63 of IC1401 on L level?) No Check SW1936, soldered joints of mechanism switch PWB, and periphery of pin 6 of CN1932.
PAGE 75
MD-MX30/MX30W • 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.
