DTS System Troubleshooting

1. Movie not playing in DTS digital sound, CP (cinema processor) won’t switch to DTS format.

Is the SYSTEM light blinking on the DTS player?

NO System is not ready to play. Ensure movie disc(s) are in the DTS player. They should match the movie playing. Turn off DTS player power switch, wait 3 seconds, switch back on. If SYSTEM light doesn’t blink, repeat test using another set of movie discs or use a DTS test disc.

•If the SYSTEM light doesn’t blink, try the DTS Setup Disc. If that won’t work, check the power.

*Verify the rear panel power switch is correctly set. Are the AUTOMATION and ANALOG cables swapped?

*Is the power supply’s fan turning? If not rotating, turn off power switch and remove player’s top cover.

•Verify the spade lugs on the power switch are securely attached.

•Use a multimeter to verify the power switch is switching correctly. Can be checked at AUX AC socket in rear panel.

•If the power switch is correctly wired and the switch tests OK, check power on the motherboard.

•On the motherboard, if the voltage from the power supply is not correct, replace the supply.

*If the voltage input to the motherboard is good, turn off power and push down all the internal boards onto their connectors. Be sure all cables are securely connected and their PIN 1 is correctly oriented. Try test again by inserting any DTS disc into player. If the SYSTEM light starts to blink, reinstall.

*If the power supply is good but the player won’t boot up, replace player.

YES * Is the player’s TIMECODE light on solid?

•If not on, is the film threaded through the DTS reader? Is DTS timecode on the print?

•Is the reader’s red LED (inside the lens) on?

•If not on, the reader isn’t getting 5v DC from the player. Verify the cable connection from player to reader. Check cable’s pin-to-pin continuity. Check for shorts or opens in cable. Check that the fuses inside the DTS player are not blown (NOTE: DTS-6D use self resetting circuit breakers).

•Is the reader’s green LED on?

•If not on, attach the grounding jumper on the reader’s timecode cable to the projector. Easiest place to do that is attach to the screw that secures the timecode cable to the reader head. The reader’s housing must be electrically connected to the projector housing. Verify with an ohm meter. This is needed for projectors that are not properly grounded.

• If grounding the projector doesn’t help, replace reader.

•If the TIMECODE light is blinking, see number 2, next page, follow steps in “Is reader’s green LED blinking?”

•If the reader’s green LED is very dim, replace the reader.

*Is the DTS player’s DIGITAL light on?

•If not on, verify only theatrical discs are in the player. Use only one movie title and trailer disc at a time.

•If not on, verify the movie discs match the movie playing. Turn DTS player power off, wait 3 seconds, and power on the DTS player. This must be done when changing movie/trailer discs.

•If not on, is a Dolby SR-D(DA10 or DA20) connected to the CP as well as DTS?

•If yes, turn the DA10/20 off, it interferes with the format switching.

•If not on, test the speed of the projector by using the DTS Projector Speed Test Disc. Follow directions included with disc.
