Page 37: Troubleshooting
MD-MS200W/MD-MS200/MD-MS200H TROUBLESHOOTING It is advisable to use the TEST mode (refer to Error Data Display Mode, P15) indicating the causes of troubles before starting repair. Causes of operation errors (up to 10 errors) are recorded as error codes. This information is useful for repair.
Page 38 MD-MS200W/MD-MS200/MD-MS200H • Abnormal display Is waveform output from CNS 402 pins 1 to 3? Is waveform output from IC 401 pins 13 to 15? Are the pin7 (VCC) and pin 6 (GND) normal? Check the periphery of IC401. Check between IC401 and CNS402.
Page 39 MD-MS200W/MD-MS200/MD-MS200H • Test mode check Insert a high reflection (low reflection) disc, and once perform automatic adjustment in AUTO mode, and then check in MANUAL mode. Simultaneously observe waveforms of EFM(TP145), FEOUT(TP143), and TEOUT(TP144). Does the optical pickup move to outer/inner periphery when...
Page 40 MD-MS200W/MD-MS200/MD-MS200H Continued from the preceding page In case of high reflection disc, proceed to the item "normal Check whether values of pins 10, 11, 14, and 15 of IC201 and playback".In case of low reflection disc, check whether pins 30 and 32 of IC101 (TP143) change when the adjustment is within allowable range in the TOTAL level button is pressed.
Page 41 MD-MS200W/MD-MS200/MD-MS200H • Normal playback When the address up to the sector address has been proved to be normal in the test mode. Is initialization performed normally in case of high reflection Does the playback time display act? disc normal playback? Check IC201 and IC202 connection line.
Page 42 MD-MS200W/MD-MS200/MD-MS200H • Recording/playback operation Insert a low reflection disc, and ascertain audio output by normal playback, and then set TEST REC mode. Check voltage of pins 56 and 57 of IC401, pins 2, 4, 7, and 9 of Does the head move down, failing to start record even IC851, pins 12 and 13 of CNS601.
