Symptom
The remote does not function.
The player uses a built-in micro computer for its various operations. Due to change in power
supply conditions, etc., operation may sometimes become unstable. After trying the above
remedies, if the player still does not function properly, unplug the AC power cord and remove
all the batteries. After all indications in the display disappear, plug the AC power cord and
insert the batteries again. If the problem persists, please consult your nearest Sony dealer.
