8. Troubleshooting
Experienced cinema engineers will have their own methods and styles of troubleshooting. Here are some
tips that relate to the SDDS format and the DFP-3000 system. Check with Sony Cinema Products for a
Tech Note with more details.
Problems with playing SDDS.
First, ensure that the film actually has SDDS tracks on it. These tracks are the light blue or cyan areas at
the outside of both rows of sprocket holes. The dark blue spots are very small, but you should be able to
see a fine granularity in this area-not just a smooth blue area.
The first indication of problems playing SDDS titles due to poor print quality or dirty optics may be
flickering of the film title displayed on the Decoder’s LCD display (SDDS Fader Automation must be
enabled to display the film title). Clean the Reader optics.
The SYSTEM OK LED on the DFP-D3000 front panel indicates that battery power is OK and that the
unit is properly communicating with its Reader. The DATA PRESENT LED will flash if film is running
through the Reader at 24 frames/second (+/- 5%) and comes on solidly when SDDS data is being received
from the Reader.
Next to the MASTER VOLUME fader is a switch labeled MUTING. If this switch is illuminated, sound
does not appear at the outputs. Press it to restore sound output.
The REMOTE LED indicates that the Decoder is being controlled through its serial port, at which time
the front panel controls and most of the AUTOMATION connector’s inputs are locked out. Be sure your
laptop software is “disconnected”.
The Reader will turn on its bright red LEDs when the black sprocket roller is turning and it is receiving
power through its cable. If the DFP-D3000 is powered and you don’t see LEDs on the Reader, check that
the Reader cable is plugged in and is not damaged.
The matrix modes described in section 6.14 can be complicated. If you have channels missing, particular-
ly the subwoofer, on a certain Preset, check that you have selected the desired matrix mode for that
Preset.
The EXT FADER button on the front panel of the DFP-D3000 enables a remote fader. If this function is
active (as indicated by its illuminated switch), the MASTER VOLUME control becomes inoperative and
the external fader takes over. Don’t use this switch unless an external fader is actually connected or your
sound may be muted.
The PROJECTOR LEDs indicate which projector’s DFP-R3000 Reader is selected in a changeover
environment, using the rear Automation connector pins. Be sure the correct Reader is selected. Optical
soundtrack reader selection is also selected at the Automation connector, but has no bearing on these LED
indicators.
