Troubleshooting guide
Before requesting service, make the following checks. If you are in doubt about some of the check points, or if the solutions indicated in the chart
do not solve the problem, consult your dealer for instructions.
Updating to the latest software (firmware) may solve the problem. (> 98)
No power.
The unit does not turn on pressing [Í].

¾ One of the unit’s safety devices is activated. Press [Í/I] on the
main unit to turn the unit on.
The power is turned off automatically.
¾ If you connected this unit to a “HDAVI Control” compatible TV
with an HDMI cable, or connected this unit to a Q Link-
compatible TV with a fully wired 21-pin Scart cable, this unit will
be automatically set to standby mode when the TV is set to
standby mode.
This unit turns off when the TV input is switched.
¾ If connected with an HDAVI Control 4 compatible TV (VIERA)
with the “Intelligent Auto Standby” setting activated on the TV,
when switching the TV input, the unit will be automatically
turned to standby. For details please read the operating
instructions of the TV.
The display is dim.
¾ Change “Unit’s Display” in the Setup menu. (> 92)
“0:00” is flashing on the unit’s display.
¾ Set the clock. (> 95)
The time recorded on the disc and the available
time shown do not add up.
The displayed time of this unit is different from
the actual recording time.
¾ Times shown may disagree with actual times.
¾ [BD-R] [-R] [-R]DL] [+R] [+R]DL] The remaining capacity does not
increase even if titles are deleted.
¾ Available recording space on DVD-RW (DVD-Video format) or
+RW increases only when the last recorded title is deleted. It
does not increase if other titles are deleted.
¾ If you record or edit about 200 times or more, the remaining
capacity of DVD-R, DVD-R DL, +R, and +R DL is reduced and
then recording or editing may be disabled (for the second layer
on DVD-R DL and +R DL, this happens after about 60 times).
¾ While searching, the elapsed time may not display correctly.
Compared to the actual recorded time, the
elapsed time displayed is less.
(Only when recording in NTSC)
¾ The displayed recording/play time is converted from the
number of frames at 29.97 frames (equal to 0.999 seconds) to
one second. There will be a slight difference between the time
displayed and the actual elapsed time (e.g., actual one-hour
elapsed time may display as approximately 59 minutes 56
seconds). This does not affect the recording.

switched to standby.

disc.
Television reception worsens after connecting
the unit.
¾ This can occur because the signals are being divided between

booster, available from audio-visual suppliers. If it is not solved
by using a signal booster, consult the dealer.
The digital channel information or Control Panel
does not appear.
