The RV-8 does not power on.
1. Make sure the rear-panel power switch is set to the | (“on”)
position.
2. Attempt to power on the RV-8 with the front-panel Standby
button and remote control On button.
3. Examine the power cord to ensure a good connection between
the rear-panel AC input connector and the wall outlet.
4. Check the electrical circuit and breaker.
The remote control does not work.
1. Eliminate obstructions between the remote control and the
front-panel IR receiver. When the RV-8 is not using the rear-
panel IR IN connector, the remote control must be in line of
sight with the front-panel IR receiver for proper operation. The
remote control might also become unreliable if strong sunlight
or fluorescent light is shining on the IR receiver.
2. Make sure the remote control batteries are correctly inserted
with the proper polarity (page 1-6).
3. Replace the remote control batteries. When the batteries are
low on power, the remote control enters a low-voltage
condition that prevents it from operating the RV-8.
The RV-8 is powered on, but there is no audio.
1. Make sure volume level is audible. Volume level can be
increased with the front-panel volume knob or the remote
control VOL and buttons.
2. Make sure audio has not been muted. The message “MUTE
ON” or “FULL MUTE ON” will appear in the on-screen and
front-panel displays when audio has been muted. To deactivate
mute, press the Mute button or adjust the volume level.
3. Check the INPUT SETUP menu DIGITAL IN and ANALOG IN
parameters to ensure the appropriate audio connector is assigned
to the selected input.
4. Make sure the RV-8 is receiving an audio signal. To do this,
follow the instructions that begin on page 2-29 to open the
STATUS menu for the current input source.
Dialogue sounds muffled.
If the speaker setup does not include a center speaker, make sure a
custom – as opposed to a THX – speaker setup is selected. Then,
make sure the CUSTOM SETUP menu CENTER parameter is set to
NONE (page 3-31).
A humming sound is present in the audio.
1. If a cable TV connection is present, disconnect the cable from
the wall outlet. If this eliminates the humming sound, a ground
loop isolation device is required. Contact your dealer or the
cable provider for assistance.
2. Disconnect components one at a time to isolate the problem.
Once the problem is identified, make sure the associated
component is properly grounded and connected to the same
electrical circuit as the RV-8.
The RV-8 is powered on, but there is no video.
1. Examine the video cables – particularly the S-Video cables –
to ensure a good connection to the associated component.
