Troubleshooting

The unit does not turn on.
• Make sure the power cord is plugged into the rear panel and a live
AC outlet.
• Make sure the rear panel POWER switch is in the ON position.
No sound from any input.
• Make sure that MUTING is off and VOLUME is turned up.
• Make sure that preamp outputs are connected to a power amplifier
and that the amplifier is turned on.
• Make sure source inputs are connected and configured correctly.
• Check that the setting for HDMI AUDIO in the VIDEO/HDMI on-
screen menu is AMP MODE.
No sound from digital sources.
• Make sure that digital input connector is assigned to the proper
source input and that the source input is configured to use the digital
input rather than an analog input.
• Check the configuration of the DVD player to ensure that the
bitstream and/or DTS digital output is activated.
No sound from some speakers.
• Check all power amp and speaker connections.
• Check Speaker Configuration settings in the Setup menus.
No video output on TV monitor.
• Make sure that the TV monitor is connected properly and check the
input assignments. S-Video and Composite Video TV monitors can
only be used with interlaced SD sources. HDMI and Component
TV monitors can be used with Standard Definition (SD) and High
Definition (HD) sources. An HDMI 1080p source can only be sent to
a 1080p-compliant TV monitor.
• Component Video output at 720p or 1080i may not be available if
the source signal includes HDCP copy protection.
• HDMI cables must be 5 meters or less in length.
OSD menus are not displayed on TV Monitor.
• In some PAL systems, the menus may not be displayed unless there is
an active video signal.

• Check that the proper video source is selected for each input.
• Check that the group delay (lip-synch) setting is not misadjusted.
Clicking or popping sounds when switching inputs.
• The unit uses relay switching to preserve maximum sound quality. The
mechanical clicking of the relays is normal.
• During switching, it may take a split second for digital signals to
be recognized and properly decoded. Rapid repeated switching
between inputs or settings can result in clicks or pops from the
speakers as the unit attempts to lock on to the rapidly changing
signals. This causes no harm.
Controls do not operate.
• Make sure that fresh batteries are installed in the remote.
• Make sure that the IR sensor on the front panel is not blocked. Aim
the remote at the sensor.
• Make sure the sensor is not receiving strong IR light (sunlight,
halogen lighting, etc.)
• Unplug the unit from the AC outlet, wait 30 seconds, and plug it back
in to reset.
No video from Zones 2, 3 or 4
• Check ZONE SETUP configuration and zone video input setting as
assigned and make sure that a Composite source is connected.

HDMI: Frequently Asked Questions

What is HDMI?
HDMI (High-Definition Multimedia Interface) is an advanced type of
connection which carries both video and audio in a single cable. It is a
modern digital replacement for older analog video connection standards
such as Composite Video, S-Video and Component Video. This Rotel unit
meets the latest version of HDMI specification, HDMI 1.3.
What is the difference between HDMi and DVI?
An earlier digital connection standard, DVI (Digital Visual Interface) can
also be used for high-definition video signals by means of a suitable
adaptor. However, unlike HDMI, the DVI connection does not also carry
audio signals, nor does it automatically set the picture screen to the
correct size.
What is the difference between HDMI 1.3 and earlier versions?
If you have a Blu-ray player, note that the HDMI 1.3 connection can
carry the new Dolby TrueHD and DTS HD Master Audio formats used
on Blu-ray discs. This receiver is able to decode and replay these 7.1
channel audio formats.
