Troubleshooting
Incorrect operations are often mistaken for trouble and
malfunctions. If you think that there is something wrong with
this component, check the points below. Take a look at the
other components and electrical appliances being used,
because sometimes the problem may lie there. If the trouble
isn’t sorted out even after going through the checks below,
ask your nearest Pioneer authorized independent service
company to carry out repair work.
• If the unit does not operate normally due to external
effects such as static electricity disconnect the power
plug from the outlet and insert again to return to normal
operating conditions.
General
The power does not turn on.
Disconnect the power plug from the outlet, and insert again.

After about a minute (you won’t be able to switch the unit on
during this time), switch the receiver back on. If the message
persists, call a Pioneer authorized independent service
company.
The power suddenly turns on or off, or the input suddenly
changes (When the Control with HDMI is ON).

subwoofer, set it to 0º (or depending on the subwoofer, the
setting where you think it has the best overall effect on the
sound).

speakers (see
Speaker Distance
