If it appears that the DVD Video player is faulty, first consult this checklist.
Something may have been overlooked. Under no circumstances should you
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).
Remedy
– Check if the on/off button on the front of the player is set to on.
– Check if there is power at the AC outlet by plugging in another appliance.
– Check if the TV is switched on.
– Select the same channel and source on the TV as on the player.
– Check the video connection.
– Check the disc for fingerprints and clean the disc with a soft cloth,
wiping from the center to the edge.
– Sometimes a small amount of picture distortion may appear. This is not a
malfunction.
– If the picture is distorted completely or if the picture rolls vertically,
make sure the NTSC/PAL setting at the DVD player matches the
video signal of your television.
– If your TV video signal is NTSC, select the NTSC setting at the DVD player.
– If your video signal is PAL, select the PAL setting.
– The disc format does not match your TV's video signal (PAL/NTSC).
– Check audio connections.
– If you are using a HiFi amplifier, try another sound source.
– Check to make sure that no audio connections are made to the
amplifier's phono input.
– Check the digital connections.
– Check the settings menu to make sure the digital output is set to ALL or
PCM.
– Check if the audio format of the selected audio language matches
your receiver capabilities.
– Ensure the disc label is facing up.
– Clean the disc.
– Check if the disc is defective by trying another disc.
– Check to see if the disc is defective, badly scratched or warped (not flat).
– Reset the unit by switching the player off, then on again.
– Check to see if the program requires another disc to be loaded.
– Aim the remote control directly at the sensor on the front of the player.
– Remove any obstacles between the player and the remote control.
– Inspect or replace the batteries in the remote control.
– In order to completely reset the player, unplug the AC cord from the
AC outlet for a few seconds.
– Operations may not be permitted by the disc. Refer to the instructions of
the disc.
