Why is there no opening screen on my Pioneer S-DV535W monitor?
If the opening screen is not displayed on the monitor of your Pioneer Receiver, check the video signal path between DVD IC (W51 DVDMAIN Assy IC201) and video-out terminal. This may require checking the W51 DVDMAIN Assy Video circuit after DVD IC (IC201).
Why is there no sound on my Pioneer S-DV535W Receiver but the picture is normal?
If you're experiencing no sound but the picture is normal on your Pioneer Receiver, check the waveform (SPDIF: CN901-pin 16). This may require checking the W51 DVDMAIN Assy DVD IC (IC201).
Why isn't the spindle turning during playback on my Pioneer S-DV535W?
If the spindle isn't turning during playback on your Pioneer Receiver, check the signals output from IC101-pin 30 (W), pin 33 (V), and pin 35 (U) on the W51 DVDMAIN Assy. Also, verify if pin 26 (STBY) is fixed LOW (it should be High at playback: 3V), which may indicate an issue with the W51 DVDMAIN Assy FTS Driver IC (IC101). Inspect the mechanism section (Spindle motor) for any detached parts or foreign objects lodged in it. Ensure the wires of CN102 on the W51 DVDMAIN Assy are neither disconnected nor damaged; if they are, check the flexible cable/connector. Check the signal output from IC201-pin 37 (DMSO) on the W51 DVDMAIN Assy, potentially indicating a problem with the W51 DVDMAIN Assy DVD IC (IC201).
What causes playback to stop on my Pioneer S-DV535W?
If playback stops on your Pioneer Receiver, it could be due to several reasons. Check if the 650-nm LD has deteriorated. If the voltage at each end of R322 and R325 on the W51 DVD MAIN Assy is 0.4 V or more, the 650-nm LD is likely deteriorated. This is more likely when playback of a DVD is impossible. Also, check if the 780-nm LD has deteriorated. If the voltage at each end of R321 and R326 on the W51 DVD MAIN Assy is 0.4 V or more, the 780-nm LD is likely deteriorated. This is more likely when playback of a CD is impossible. Check for abnormalities in the FG waveform at IC201-pin 47, potentially indicating an issue with the W51 DVDMAIN Assy FG output : FTS Driver IC (IC101). Finally, inspect the disc for scratches or dirt.
Why is my Pioneer S-DV535W Receiver unable to focus during playback?
If your Pioneer Receiver is unable to focus during playback, check the signals output from IC101-pin 3 (FOCS_DRV) and pin 4 (FOCS_RTN) on the W51 DVDMAIN Assy, as this could indicate a problem with the W51 DVDMAIN Assy FTS Driver IC (IC101). Verify if the 650-nm LD emits light, the pickup lens moves up/down, and the actuator spring bends, which could point to a pickup issue. Inspect the mechanism section (motor) for damaged plastic parts, detached shafts, or a detached/tilted turntable. Ensure the flexible cable of CN101 on the W51 DVDMAIN Assy is neither disconnected nor damaged; if it is, check the flexible cable/connector. Check the signal output from IC201-pin 42 (FOSO) on the W51 DVDMAIN Assy; it should typically output about 1.4 V, fluctuating by about ± 250 mV with focus up/down, po...
