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.

No power.

The unit does not turn on pressing [Í].

¾ Insert the AC mains lead securely into a known active

household mains socket. (> 8, 67)

¾ Linked timer recordings with external equipment is in recording

standby (“EXT-L” on the unit’s display blinks when [Í] is

pressed). Press [EXT LINK] to cancel the recording standby.

(> 23)

The unit switches to standby mode.

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. (> 34)

This unit turns off when the TV input is switched.

¾ This is a normal phenomenon when using VIERA Link (HDAVI

Control 4 or later). For details please read the operating

instructions for the TV.

The display is dim.

¾ Change “Unit’s Display” in the Setup menu. (> 62)

“0:00” is flashing on the unit’s display.

¾ Set the clock. (> 64)

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 or MP3 recording time.

¾ Times shown may disagree with actual times.

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 Even if you delete recorded content from the DVD-R, DVD-R

DL, +R or +R DL, there is no increase in disc space.

¾ More disc space than the actual recording time is used after

recording or editing the DVD-R, DVD-R DL, +R or +R DL 200

times or more.

¾ While searching, the elapsed time may not display correctly.

The clock is not correct.

¾ Under adverse reception conditions, etc., the automatic time

correction function may not work. In this case, “Automatic” is

automatically turned to “Off”. If re-setting the Auto Clock Setting

does not work, set the time manually. (> 64)

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

1 second. There will be a slight difference between the time

displayed and the actual elapsed time (e.g., actual 1 hour

elapsed time may display as approximately 59 minutes

56 seconds). This does not affect the recording.

“U88” is displayed and the disc cannot be

ejected.

¾ The unit is carrying out the recovery process. Do the following

to eject the disc.

1 Press [Í/I] on the main unit to switch the unit to standby.

If the unit doesn’t switch to standby, press and hold [Í/I] on

the main unit for about 3 seconds. The unit is forcibly

switched to standby.

While the unit is off, press and hold [

∫

] and [CH

]

on the main

unit at the same time for about 5 seconds. Remove the disc.

Television reception worsens or becomes

impossible after connecting the unit.

¾ This can occur because the signals are being divided between

the unit and other equipment. It can be solved by using a signal

booster, available from audio-visual suppliers. If it is not solved

by using a signal booster, consult the dealer.

¾ Broadcast signals may not be output from this unit’s RF OUT

terminal. Select “On” in “RF OUT ( Aerial Signal )” in the Setup

menu. (> 65)

Some functions of DVB-T do not work.

¾ The unit does not necessarily support all DVB-T functions such

as MHP (Multimedia Home Platform) etc.

New functions introduced by broadcasters cannot be

guaranteed to work.

Screen size is wrong.

¾ Check the settings for “TV Aspect” in the Setup menu. (> 63)

¾ If you connect an HDMI cable, set “Aspect for 4:3 Video” to

“16:9” in the Setup menu. (> 63)

The recorded title’s screen size is wrong.

¾ Set “Rec for High Speed Copy” to “On”, and set the “Aspect for

Recording” to “4:3”. (> 61)

¾ 16:9 aspect programmes are recorded in 4:3 aspect in the

following cases.

– [-R] [-R]DL] [-RW‹V›] If you recorded or copied using “EP” or “FR

(recordings 5 hours or longer)” recording mode.

– If you recorded or copied to a +R, +R DL or +RW.

– If you recorded with the “Aspect for Recording” set to “4:3” in

the Setup menu.

When you want to record 16:9 programme in the same

aspect, set “Rec for High Speed Copy” to “On”, and set the

“Aspect for Recording” to “16:9”. (> 61)

By setting “Aspect for Recording” to “Automatic”, there is a chance

that the recording will be made using the wrong aspect. Match the

aspect settings to the broadcast when recording. (

It may be possible to adjust the display mode on the TV. Refer to

your television’s operating instructions.
