Troubleshooting
If it appears that the DVD Recorder is faulty, first consult this checklist. It may be that something has been overlooked.
Under no circumstances attempt to repair the system yourself; this will invalidate the warranty. Look for the specific
symptom(s). Then perform only the actions listed to remedy the specific symptom(s).
Symptom Remedy
The Recorder does not respond to the
remote control Aim the remote control directly at the sensor on the front of the Recorder.
Avoid all obstacles which may interfere with the signal path.
Inspect or replace the batteries in the remote control.
No power Make sure power cord is properly connected.
Check if there is power at the AC outlet by plugging in another appliance.
No picture Check if the TV is switched on.
Check the video connection.
Distorted picture / distorted sound Check the disc for fingerprints and clean the disc with a soft cloth, wiping
from the center to the edge in a straight line.
Sometimes a small amount of picture distortion may appear. This is not a
malfunction.
Recorder does not play disc Ensure the disc label is facing upward and the right disc type is inserted.
Clean the disc.
Check if the disc is defective by trying another disc.
Check if the region code of the disc matches the region code of the
Recorder (pre-recorded DVD discs only). See ‘playing a pre-recorded DVD-
Video disc.’
Check if Child Lock is activated.
No sound Check audio connections.
If using a HiFi amplifier, try another sound source.

the digital output of the DVD Recorder.

Buttons on the DVD Recorder do not work Disconnect and reconnect the DVD Recorder from the power outlet. If this
does not solve the problem, check if the remote control still works. If so, the
Recorder is probably in trade mode. Disconnect the Recorder from the
power source and reconnect it while pressing and holding / and 9 for a few
seconds.
Recorder does not respond to all operating
commands during playback Some operations are not permitted by the disc. Refer to the instructions in
the disc jacket or case.

menu (message: ‘Disc locked’ on screen).
