The display is dim.
≥Change “Front Display” in the SETUP menu.

“12:00” is flashing on the 
unit’s display.
≥Set the clock.

Compared to the actual 
recorded time, the remaining 
time displayed is less.
≥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 slight a 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.
The time recorded on the disc 
and the available time shown 
do not add up.
The play time shown for MP3 does 
not agree with the actual time.
≥Times shown may disagree with actual times.
≥More disc space than the actual recording time is used after recording or editing the DVD-R 
200 times or more.
≥While searching, the elapsed time may not display correctly.
≥Even if you erase recorded content from the DVD-R, there is no increase in disc space.


Television reception worsens 
after connecting the unit.
≥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.
Status messages do not appear.
≥Select “Automatic” in “Status Messages” in the SETUP menu.

The blue background does not appear.
≥Select “On” in “Blue Background” in the SETUP menu.
41
The 4:3 aspect ratio picture 
expands left and right.
Screen size is wrong.
≥Use the television to change the aspect. If your television does not have that function, set 
“Progressive” in the Video menu to “OFF”.
≥Check the settings for “TV Type”, “4:3 TV Settings for DVD-Video” or “4:3 TV Settings for 
DVD-RAM” in the SETUP menu.

There is a lot of after-image 
when playing video.
≥Change the settings for “3D NR”, and “Integrated DNR” to “0” or turn “MPEG-DNR” off if it is 
on.
25
When playing DVD-Video using 
progressive output, one part of 
the picture momentarily 
appears to be doubled up.
≥Set “Progressive” in the Video menu to “OFF”. This problem is caused by the editing method 
or material used on DVD-Video, but should be corrected if you use interlace output.
25
There is no apparent change 
in picture quality when 
adjusted with the Video menu 
in the on-screen menus.
≥The effect is less perceivable with some types of video.
The images from this unit do 
not appear on the television.
Picture is distorted.
≥Make sure that the television is connected to the VIDEO OUT terminal, S-VIDEO OUT 
terminal or COMPONENT VIDEO OUT terminals on this unit.
≥Make sure that the television’s input setting (e.g., VIDEO 1) is correct.
≥The television isn’t compatible with progressive signals. Press and hold [∫] and [TIME SLIP] 
on the main unit at the same time for about 5 seconds. The setting will change to interlace.
