What to do if the opening screen is not displayed on Pioneer XV-DV370 Receiver?
If the opening screen is not displayed on your Pioneer Receiver, check the video signal path between DVD IC (DVD MAIN Assy IC201) and video-out terminal (see the block diagram).
What to do if there is picture disturbance during Pioneer Receiver playback?
If you experience picture disturbance such as block noise or freezing during playback on your Pioneer Receiver, check the disc for scratches or dirt. Also, verify that the disc format is compatible. You can 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 playback stops on Pioneer XV-DV370 Receiver?
If playback stops on your Pioneer Receiver, check if the 650-nm LD has deteriorated. If the voltage at each end of R322 and R325 on the DVD MAIN Assy is 0.4 V or more, the 650-nm LD has definitely deteriorated. Also, check if the 780-nm LD has deteriorated. If the voltage at each end of R321 and R326 on the DVD MAIN Assy is 0.4 V or more, the 780-nm LD has definitely deteriorated. Check for any abnormality in FG waveform (IC201-pin 50). Ensure the disc is free of scratches or dirt.
How to fix a Pioneer XV-DV370 tray that won't open?
If the tray of your Pioneer Receiver won't open, check if the voltage of CN104-pin 3 and pin 5 on the DVD MAIN Assy changes normally. Pin 3 (SW2(TRIN)): Tray is fully closed: "L" Pin 5 (SW1(TROUT)): Tray is fully opened: "L". Also, check if the signal is input into IC101-pin 11 (TROPEN) on the DVD MAIN Assy. At open: 3.3V, At close: 0V. Check if the signals are output from IC101-pin 1 and pin 2 (CN103-pin 1 and pin 2) on the DVD MAIN Assy. Pin 2: Approx. 6V during opening tray approx. 0V during closing tray. Pin 1: Approx. 0V during opening tray approx. 6V during closing tray. Verify that wires of CN104 and CN103 on the DVD MAIN Assy are not disconnected or damaged. Check whether the voltage of CN102-pin 1 on the DVD MAIN Assy changes to 0V by pressing the Inside switch.
How to troubleshoot Pioneer XV-DV370 Receiver when playback is impossible due to no focusing?
If playback is impossible on your Pioneer Receiver due to no focusing, check if the signals are output from IC101-pin 3 (FOCS_DRV) and pin 4 (FOCS_RTN) on the DVD MAIN Assy. Verify that the 650-nm LD emits light, the pickup lens moves up/down, and the actuator spring bends. Inspect plastic parts for damage, ensure the shaft is attached, and check if the turntable is detached or tilted. Verify that the flexible cable of CN101 on the DVD MAIN Assy is neither disconnected nor damaged. Check if signal output from IC201-pin 42 (FOSO) on the DVD MAIN Assy. (Device control of about 1.4 V is output usually. It is fluctuated by about 250 mV with focus up / down.)
What to do if the spindle does not turn on Pioneer XV-DV370 Receiver?
If the spindle does not turn on your Pioneer Receiver, check if the signals are output from IC101-pin 30 (W), pin 33 (V) and pin 35 (U) on the DVD MAIN Assy. Check if pin 26 (STBY) is fixed LOW (pin 26 is High at playback: 3V). Also, verify that there are no detached parts from the spindle motor or any foreign objects lodged in it. Ensure that wires of CN102 on the DVD MAIN Assy are not disconnected or damaged. Check if signal output from IC201-pin 37 (DMSO) on the DVD MAIN Assy.
What to do if opening screen is not displayed on Pioneer XV-DV370 Receiver, but the FL display lights?
If the opening screen is not displayed, but the FL display lights on your Pioneer Receiver, check if the signals are output from IC201-pin 97 (MDATA) and pin 98 (SCLK) on the DVD MAIN Assy (in the range of 0-3V). Also, check if the signals are input into IC5501-pin 50 (MDATA) and pin 51 (SCLK) on the DVD MAIN Assy (in the range of 0-3V). Check that the following voltage are output : Q1302-collector on the DVD MAIN Assy: 5V. Verify if a resonator (X201: 27MHz) on the DVD MAIN Assy is oscillating. Check if a signal output from IC203-pin 28 (PRD#) on the DVD MAIN Assy? (Is a signal fluctuating for several hundred mS after the power is turned on ?). Check if a signal is input into IC5501-pin 67 (DVD ACK) on the DVD MAIN Assy ? (Is a signal fluctuating ?) -> Communication with FL Control IC. Ch...
