Why is no opening screen displayed on my Pioneer DVD Player (FL display lights, mechanism doesn't work)?
If the FL display lights up but no opening screen appears and the mechanism isn't working, check the video signal path between the DVD IC (DVD MT Assy IC4002) and the video-out terminal.
How to troubleshoot power not turning on for Pioneer DVD Player?
To troubleshoot why the power isn't turning on, check the voltage of A1T+3.35V, –28V, and FLDC on the POWER SUPPLY Unit. Also, verify if the wires of the output connector (POWER PCB ASSY) and CP4003 (DVDM Assy) are disconnected or damaged. Check that the voltage at IC101-pin 22 (KEY0) on the FLKY Assy becomes about 2.7V when the POWER key is pressed and 0 V when it is released. Check that the voltage at OS651-pin 1 (IR) on the OPERATION1 Assy is in the range between 0 and 3.3 V while receiving signals from the remote control unit when any key on it is pressed.
What to do if no opening screen is displayed on Pioneer DV-380-S DVD Player monitor (FL display lights, mechanism doesn't work)?
If the FL display lights up, but no opening screen appears on the monitor and the mechanism isn't working, you can check these voltages on the POWER SUPPLY Unit: * E+6.8V * SW+3.3V Also, verify that the voltage of P.ON-H is about 2.8V on the POWER SUPPLY Unit. Check that the following voltage are output : IC4006-pin 5 : 1.8V, on the DVD MT PCB Assy. Check if a resonator (X4001 : 27MHz) on the DVDM Assy oscillating. Check if a signal input into IC603-pin26 (PCE#) on the DVDM Assy ? (Is a signal "H" for 80 mS and then "L" after the power is turned on?). Check if the signals input into IC4005-pin 16 (DWE#), pin 19 (DCS#) and pin 38 (SDCLK) on the DVDM Assy ? (Is a signal fluctuating?). Check if a signal output from IC4004-pin 28 (PRD#) on the DVD MT Assy? (Is a signal fluctuating for se...
