• 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 en able 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.
• O
n 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
