the interior. Remove any screws securing the front panel and remove the
panel. If it won't move, check beneath it for clips or additional screws.

tray and gently pull the tray out of the player. Clean the travel rail and
guides with a swab dampened with denatured alcohol. Lubricate lightly with
white lithium grease.

lint-free cloth moistened with denatured alcohol. If the belt is damaged,
replace it. Service a DVD tray motor:

the end of each bale and lift out the motor. Replace the motor if
necessary.
