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 Onkyo authorized independent service
company to carry out repair work.

such as static electricity disconnect the power plug from
