    MD-X5H/CP-X5H 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.
  • Page 70 MD-X5H/CP-X5H • The CD operation button operates. Check the FOCUS-HF system. Playback is enabled without disc. Focus search OK Does the pickup move up and down two times? Check the IC5 to CNP2 and periphery. Is the output waveform of IC1 pin 16 (FD) identical with that shown in Figure 70-1? 0.5s...
  • Page 71 MD-X5H/CP-X5H • Check the tracking system. Check the waveform of IC1 pin 7 (TE). Check the periphery from the IC1 pin 8 The waveform shown in Figure 71 appears. The tracking servo does not The discless state appears soon. to pin 15, from IC5 to CNP2.
  • Page 72 MD-X5H/CP-X5H • Check the VCO-PLL system. Playback operation is performed when disc exists. Although the HF waveform is normal, the TOC data cannot Check the PDD waveform. (Figure 72) be read. Abnormal Check the IC1 pin 43, pin 44, IC2 pin 3, pin 5, pin 7, pin 10, and pin 11.

    MD-X5H/CP-X5H TROUBLE SHOOTING (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.
  • Page 74 MD-X5H/CP-X5H • Disc loading is not normal. Is disc loaded when it is inserted? Check CNP1601 and SW1956. Is the pin 4 of CNP1601 set to L state? Is change observed on the pin 23 or 24 of IC1601? Check IC1401.
  • Page 75 MD-X5H/CP-X5H • 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 Does the playback time display advance? played back? Check IC1201 Does disc rotate normally?
  • Page 76 MD-X5H/CP-X5H • Record and playback operation Insert the low reflection disc, and after verifying the audio output in the normal mode playback set the record/playback TEST mode Recording from start address cannot be performed. Check whether the disc is record-prohibited.
  • Page 77 MD-X5H/CP-X5H • Disc motor fails to run Check soldering joint and parts of pins 24 and 25 of IC1201, and Does waveform appear on the pins 24 and 25 of IC1201 in the peripheral circuit. TEST mode focus gain coarse adjustment step?
