Before requesting service, make the following

check points, or if the solutions indicated in the
following guide do not solve the problem, consult
your dealer for instructions.
The unit does not work.
Operations are not done properly.
1 Touch [Í/I] on the main unit to turn it off.
≥ If the main unit still does not turn off, touch and hold
[Í/I] on the main unit for at least 5 sec. This will force
turn off the main unit. Alternatively, disconnect the AC
mains lead, wait for at least 3 minutes, then reconnect
it.
2 Touch [Í/I] on the main unit to turn it on.
(It may take some time for the main unit to be
turned on.)
Consult your dealer if the problem persists.
No power.
≥ Unplug the AC mains lead for at least 3 minutes
before plug in again.
≥ After turning the main unit on, if the main unit
immediately turns off, unplug the AC mains lead
and consult your dealer.
≥ If the main unit does not turn on by turning on
TV (HDAVI Control), turn on the main unit
manually.
If the problem persists, refer to “HDMI” in
“Troubleshooting”.
The remote control does not work properly.
≥ The battery is depleted. Replace it with a new
one. (> 7)

≥ It may be necessary to set the code of the
remote control again after changing the battery
of the remote control. (> 17)
≥ Use the remote control within the correct
operation range. (> 7)
The main unit is automatically switched to
standby mode.
“AUTO OFF” function is on.
The main unit will automatically switch to standby
mode when no signal is input and no operation is
performed for approx. 20 minutes. Refer to page
20 to turn this function off.
The main unit is turned off when the TV’s
speakers are selected in the speaker control.
This is a normal feature when using VIERA Link
(HDAVI Control 4 or later). Please read the
operating instructions for the TV for details about
its power save feature. (> 22)
The switches on the main unit do not work.
[Í/I], [VOL j], [VOL i], [INPUT], and [ ] on the
main unit are touch keys. Touch the switches with
your finger. They may not work if operated with
your fingernails or hands wearing gloves.
Colour irregularities on a CRT TV.
If colour irregularities appear on the TV, turn off
the TV for about 30 minutes and move TV away
from this unit slightly. If this does not fix the
problem, move this unit away from the TV.
The TV remote control does not work even
when the IR Blaster is connected to the main
unit.
When the TV receives signals from both its
remote control and the IR Blaster, their signals
may interfere with each other, making it
impossible for you to operate the TV. Adjust the
angle at which you operate the TV remote control.

the factory preset. To change the remote
control code, refer to “Remote control code”
