The picture below shows the DVD Player Power Supply PWB separated from the DVD
Player. This allows access to the connectors and for Troubleshooting the Power Supply. Re-
turn to the DVD player Troubleshooting Index to see Flow Charts.
This picture shows how to check for AC applied to the Power Supply PWB. Other checks can
be made this way and access to the check points are made much easier with the Power Supply
separated from the DVD player.
By plugging in the PPV connector AC is applied and the on board power supply can operate.
The PVS1 must also be connected so that STBY +5V (from the PTV) can be applied to pin 2.
Or an ex5V can be used. Note: Pins 5 and 8 of PVS1 is used as ground.
To turn on the Power Supply, apply a 2.2 K ohm resistor between pin 2 (+5V) and pin 3
(Power On 3). This simulates a Power On command from the PTV microprocessor. This will
activate the relay driver (QU94) to turn on the DVD power supply. At this point, check the
following voltages.
DVD +9V
: PAA1 connector pin 14 and 15. This checks IU96.
DVD +5V
: PAA1 connector pin 13. This checks IU95.
DVD +1.5V
: PAA1 connector pin 1, 2 and 3. This checks IU94.
DVD +3.3V
: PAA1 connector pin 4 and 5. This checks EU91 protector.
