FACTORY RESET SOFTWARE UPDATE TROUBLE SHOOTING AND POWER SUPPLY CIRCUIT 

To Reset this Player
# If this Player receives strong interference from a source such as excessive static electricity, strong external noise, malfunction of power supply, or voltage caused by lightning during use or a wrong operation is sent to the Player, errors like the Player not accepting an operation may occur. Press and hold STANDBY/ON on the Player until "RESET" appears on the front panel display when the Player does not operate properly even after the power has been turned off. Then turn on the power again.
# It may take several minutes until completion as the system check will be executed when the power is turned ON. Please wait until the indicator lights up in this case.
# Since all settings including the language setting stored in memory are also reset when a reset has been performed, they must be set again.
# When the problem persists even after performing a reset, unplug the AC cord and plug it in again. If this does not solve the problem, contact the nearest service center approved by Pioneer.

1. Select "SHIP" then "ON" on the menu, using the [UP/DOWN/LEFT/RIGHT] key on the supplied remote control unit, then press the ENTER key.

2. The unit automatically turns off and on. The On Screen Language setting screen is displayed,Select the language.

TROUBLE SHOOTING
Power does not come ON.
Is the 12V power supplied to pins (2, 3 and 4) of P9001 inside MAIN PWB-S (AT_12V) while AC is ON and the power source is OFF >>The POWER Assy is normal. (12V power is supplied.) Replace and check MAIN PWB-S.
Disconnect the P9001 connector on the MAIN PWB-S after turn the power off, then do not pins 2 and 5 of P9001 on the MAIN PWB-S short-circuit >>Replace and check the MAIN PWB-S. (Short-circuit is being caused in the MAIN PWB-S.).
Is the 12V power supplied to pins (2, 3 and 4) of CN901 on the POWER Assy (AT_12V) while AC is ON and the power source is OFF >>Replace and check the POWER Assy. (The circuit up to 12 V generation in the POWER Assy has broken down.).
Check between CN901 on the POWER Assy and P9001 on the MAIN PWB-S and their peripheral circuits. (e.g. nearly detached connector, disconnection).
BD drive does not operate properly.
Does the problem (discs cannot be played back stably) happen only to certain discs >>
(In case discs cause the problem)
1 Check any dirt on discs.
2 Check whether the problem is disc-specific.
Does the problem happen only to BD, DVD or CD >>(In case LD breakdown etc. causes the problem) Replace and check BD drive.
Is the error rate wrong >>
(In case the problem derives from PU breakdown or disc-related factors)
1 Check any dirt on discs
2 Check whether the problem is disc-specific
(e.g. Pirated edition)
3 Replace and check BD drive
1 Check the drive relay board (BRIDGE Assy) and circuits around CN101 and CN104. Check any connector nearly detached or obliquely inserted. Check any disconnected pattern etc.
2 Replace and check MAIN PWB-S.
3 Replace and check BD drive.
Discs cannot be played back stably.
Does SLED motor initialize while the power is ON >>
1 Check the drive relay board (BRIDGE Assy) and circuits around CN101 and CN104.
Check any connector nearly detached or obliquely inserted.
Check any disconnected pattern etc.
2 Replace and check MAIN PWB-S.
3 Replace and check BD drive.
Does it load >>
1 Check the drive relay board (BRIDGE Assy) and circuits around CN102 and CN104.
Check any connector nearly detached or obliquely inserted.
Check any disconnected pattern etc.
2 Replace and check MAIN PWB-S.
3 Replace and check BD drive.
Does the spindle revolve when a disc is inserted.
1 Check the drive relay board (BRIDGE Assy) and circuits around CN103 and CN104.
Check any connector nearly detached or obliquely inserted.
Check any disconnected pattern etc.
2 Replace and check MAIN PWB-S.
3 Replace and check BD drive.
How to open the tray when the power cannot be turned on
When the tray cannot be opened because the power cannot be turned on, it can be opened using the emergency disc ejection rod (GGF1529). (A long, thin rod about 1 mm in diameter can be used in place of the rod.) Bend the emergency disc ejection rod at aright angle, and insert it horizontally into a hole as shown in the figure.
