What to check on a Pioneer Stereo System if there is no sound but the picture is normal?
If you're getting a picture but no sound on your Pioneer Stereo System, check the waveform (SPDIF: CN901-pin 16).
How to troubleshoot power issues on a Pioneer Stereo System?
If your Pioneer Stereo System isn't turning on, first, check the wires of the output connector (POWER SUPPLY Unit) and CN901 (DVDM Assy) for disconnections or damage. If the wiring is intact, verify that the voltage output at the + side of C739 is 3.3V. If not, the DVDM Assy 3.3V Regulator IC (IC341) might be the issue.
What causes focusing issues during playback on a Pioneer Stereo System?
If your Pioneer Stereo System can't focus during playback, check these potential causes: * Are the signals output from IC101-pin 3 (FOCS_DRV) and pin 4 (FOCS_RTN) on the DVDM Assy? * Does 650-nm LD emit light? Does a pickup lens move up / down? Does an actuator spring bend? * Are plastic parts damaged? Or is a shaft detached? Is the turntable detached or tilted? * Is flexible cable of CN101 on the DVDM Assy disconnected or damaged? * Is signal output from IC201-pin 42 (FOSO) on the DVDM Assy? (Device control of about 1.4 V is output usually. It is fluctuated by about ± 250 mV with focus up / down.)
Why does the spindle not turn during playback on my Pioneer XV-EV500 Stereo System?
If the spindle isn't turning on your Pioneer Stereo System, here's what to check: * Are the signals output from IC101-pin 30 (W), pin 33 (V) and pin 35 (U) on the DVDM Assy? Is pin 26 (STBY) fixed LOW? (pin 26 is High at playback: 3V) * Is there any part detached from the spindle motor? Or Is there any foreign object lodged in it? * Are wires of CN102 on the DVDM Assy disconnected or damaged? * Is signal output from IC201-pin 37 (DMSO) on the DVDM Assy?
What to do if playback stops on my Pioneer XV-EV500 Stereo System?
If playback stops unexpectedly on your Pioneer Stereo System, consider the following: * Does 650-nm LD deteriorate? If the voltage at each both ends of R322 and R325 on the DVDM Assy is 0.4 V or more, the 650-nm LD is definitely deteriorated. * Does 780-nm LD deteriorate? If the voltage at each both ends of R321 and R326 on the DVDM Assy is 0.4 V or more, the 780-nm LD is definitely deteriorated. * Is there abnormality in FG waveform? (IC201-pin 47) * Are there scratches or dirt on the disc?
Why is there picture disturbance during playback on my Pioneer Stereo System?
If you're experiencing picture disturbances like block noise or freezing during playback on your Pioneer Stereo System, check if there are scratches or dirt on the disc, or if there's a problem with the disc's format. Also, check the video signals: Composite video signal (IC401-pin 25) S video signal (IC401-pin 21, pin 26) RGB video signal (IC401-pin 16, pin 18, pin 20).
What to do if the tray of my Pioneer Stereo System won't open?
If the tray of your Pioneer Stereo System won't open, start by checking the voltage at CN104-pin 3 and pin 5 on the DVDM Assy. Pin 3 should be "L" when the tray is fully closed, and pin 5 should be "L" when the tray is fully opened. Also, ensure the signal input into IC101-pin 11 (TROPEN) on the DVDM Assy is 3.3V when open and 0V when closed. Check that the signals output from IC101-pin 1 and pin 2 (CN103-pin 1 and pin 2) on the DVDM Assy are approximately 6V during opening tray and approximately 0V during closing tray for Pin 2, and approximately 0V during opening tray and approximately 6V during closing tray for Pin 1. Check the wires of CN104 and CN103 on the DVDM Assy for disconnections or damage. Finally, verify if the voltage of CN102-pin 1 on the DVDM Assy changes to 0V when pressin...
Why is the opening screen not displayed on my Pioneer XV-EV500?
If your Pioneer Stereo System's opening screen isn't showing, but the FL display lights up and the mechanism doesn't work, check the following: * Are the signals output from IC201-pin 98 (MDATA) and pin 99 (SCLK) on the DVDM Assy (in the range of 0-3V)? * Are the signals input into IC5501-pin 50 (MDATA) and pin 51 (SCLK) on the IFAF Assy (in the range of 0-3V)? * Check that the following voltage are output: IC751-pin 1 on the DVDM Assy: 5V * Is a resonator (X201: 27MHz) on the DVDM Assy oscillating? * Is a signal input into IC203-pin26 (PCE#) on the DVDM Assy? (Is a signal "H" for 80 mS and then "L" after the power is turned on ?) ? Communication with flash ROM. * Is a signal output from IC203-pin 28 (PRD#) on the DVDM Assy? (Is a signal fluctuating for several hundred mS afte...
