•Noise bursts are heard when DTS encoded CDs or LDs are played. Compressed DTS data uses the normal digital audio tracks of CDs and LDs. This analog noise may be heard in your system before the DTS digital signal is locked on, or it may appear as a background hiss. To reduce or prevent this noise, disconnect any analog connections to your CD, DVD, or Laserdisc players. Just use the Digital connections and see if this addresses the problem.

No On Screen Display

See page 34 and 40

•Press the remote’s MENU button to activate the OSD. It should be present even when no video source has been selected. Remember, there is no OSD “Pop Up” for component video connections.

Sound Drops Out With CD or DVD Playback

•Make sure the disc is not dirty or scratched.

•Some inexpensive players and changers tend to mistrack more often, causing dropouts with an external DAC.

Remote Won’t Learn Commands or Codes

See page 31

•Make sure you are pointing the original remote into the receiving window of the Sherbourn remote. This is located on the top edge of the remote.

•Try touching and holding the first button to be learned.

•Do not do the learn procedure in bright lighting or sunlight.

•Make sure the Sherbourn remote is correctly in its LEARN mode. Make sure the batteries in the remote are fully charged.

•Try varying the distance between the remotes from 1 to 2 inches, and see if the learn procedure improves.

Remote Not Working

See pages 30-33

•Make sure the batteries are not dead, or installed incorrectly.

•Make sure the remote is set on the correct device display for the component you are trying to control.

•Make sure that the buttons have not been erased or learned over.

•Make sure that the PT-7010A front panel receiver window is not obstructed.

•Check that the front or rear IR receivers have not been turned off in the OSD CONTROL menu.

ZONE 2 Not Working

See pages 30 and 37

•Zone 2 is set “disabled” from the factory, so you must use the OSD Zone 2 menu on page 37 to enable it when

you are ready to use it. This enables Zone 2, but it does not turn it on.

•Once Zone 2 is enabled, use the remote control’s Zone 2 device button, followed by the Power button to turn Zone 2 on. Alternatively, press the front panel Zone 2 button, followed by the main Power button. The front panel Zone 2 Power light will be on when the zone is active (i.e. engaged and on). The Zone 2 Adjust light turns on when the zone is being adjusted. For example, if you turn Zone 2 on with the remote, and adjust the volume, Zone 2’s volume changes, and the Zone 2 Adjust light will be on.

Zone 2 Does Not Play Digital Inputs

•Zone 2 can play analog sources independent of what is playing in the Main Zone. It cannot play from a digital- only source unless that input is selected and playing in the Main Zone. To play a source such as a DVD player in Zone 2 independent of the Main Zone, make sure you connect the player’s L/R analog audio output to the PT-7010A too.

External Amplifier(s) Shut Down (Often or Prematurely)

Check the following:

•Make sure each speaker’s average impedance is not less than your amplifiers can safely handle.

•The amplifier(s) have good ventilation, no vents are covered.

•Try setting all the speakers to SMALL and let your subwoofers handle the heavy bass.

•Check that the amplifier(s) power output is a good match for your speakers. If your speakers are inefficient, consider using larger power amplifiers.

•Make sure all wiring is correct and there are no shorts.

PT-7010A “Locks Up” (No Response)

•Unplug AC power momentarily, and press Power to turn back on.

•If this does not work, try the reset procedure.

Reset Procedure

The PT-7010A is a microprocessor controlled device of great complexity. Occasional power fluctuations and spikes may cause the PT-7010A to “lock up” or act strangely. The PT-7010A can be reset as follows.

•On pages 56-58, write down your calibration settings, input settings, Tuner presets, and any other settings you have made.

•Press the power button to turn the unit off, or turn it off from the wall for a moment.

•Press and continue to hold down the front panel Power button and the Tone DOWN button at the same time. The PT-7010A will power on and cycle through the
