D-A03 TROUBLESHOOTING OF MD (Hong Kong model) When MD Inoperative Clean the object lens first then check the playback function because no operation may be caused by dirty object lens of the optical pickup. Follow the steps below if it's still inoperative after the cleaning. When the object lens is unclean with dust or etc., problems such as skipping or no TOC indication may happen. Check whether the lens is clean or not before adjustment, and clean as follows if it's dirty.

Yes When reset power on, does pulse signal enter into 6pin of CN1501 ? No Check System PWB and CN1501. Yes No Is the voltage at 62pin of IC1401 +3.2V ? Check around Q1804 and IC1401. Yes Does pulse signal 8.4672MHz add to 15pin of IC1401 ? Yes No Check IC1201.
D-A03 Recording/playback Operation Set to Rec/play Test Mode after confirming audio output at playback with low ref. disc insertion. No No recording from the start address. Isn't the disc set to record prohibited position ? Yes Is there RF waveform at TP1201 or 1pin of IC1201(Mecha.) when playback after recording ? Yes No Is there any level change between recording and playback at 3, 26, 39pin of IC1401? No Check IC1401 peripherals. Yes No Is there RF waveform at 50pin of IC1201(Mecha.
