How to troubleshoot power issues on a Pioneer DVD Player?
- NNancy CruzJul 30, 2025
If the Pioneer DVD Player's power isn't turning on, verify the voltages of AT+3.35V, –28V, and FLDC on the POWER SUPPLY Unit. Also, check if the wires of the output connector (POWER PCB ASSY) and CP4003 (DVDM Assy) are disconnected or damaged. Ensure that the voltage at IC651-pin 10 (K1) on the FLKY Assy is approximately 2.7 V when the POWER key is pressed and 0 V when released. Finally, confirm that the voltage at OS651-pin 1 (IR) on the OPERATION1 Assy is between 0 and 3.3 V while receiving signals from the remote when any key is pressed.
