Troubleshooting
3. Go over all component connections slowly and methodically.
Double-check the settings on your remote.
Wrong or loose connections are the most likely cause of the most
common home entertainment problem: no sound. Use the Connec-
tion and Setup Guide to double-check your connections for each com-
ponent. This is especially important with VCRs, tape decks, MD re-
corders, and equalizers, where it’s very easy to swap the “play” and
“record” connections.
For the KRF-X7775D you should also check your Remote Control unit
settings carefully. Did you set the input to the correct component?
(you can also check the front panel of the receiver) Are you trying to
listen to an analog source using a digital connection?
4. Cables (especially old ones) go bad more frequently than com-
ponents do.
Always suspect the cable before its component. For one thing, it’s easier
to test: simply swap the cable with one connected to a component
you know is working. If the problem component works now, it was
the cable. You can generally purchase new cables at most home elec-
tronics stores, or via the Internet.
5. User error is more likely than component failure.
You probably don’t want to hear this, but it’s true. Use this manual to
go over the steps to operate the receiver. Refer to the other compo-
nents’ manuals as well.
6. Instruction manuals are your friend.
A good rule of thumb is to check the manual when something doesn’t
work how you expected it to. If you read the manual before calling
the store or taking the component back, you may find the solution to
your problem much more quickly.
The rest of this chapter presents some common problems, grouped by
type, and the steps you can take to resolve them.
