Troubleshooting
There are no lights on the unit:
Check that:
n
  the power cord is plugged into the AVR300 and the 
mains socket outlet it is plugged into is switched on.
n
  the power button is pressed in.
n
  the mains fuse in the plug (if applicable) has not 
blown. The AVR300 requires a 6-amp fuse, or greater.
If a red LED is present, the AVR300 is in stand-by mode. 
Press any source button on the front panel or on the remote 
control.
The unit responds erratically or not at all to the 
remote control:
Check that:
n
  there are fresh batteries in the remote control.
n
  the Remote IR receiver is visible (this is located in the 
middle of the front-panel display) and that you are 
pointing the remote control towards it.
The front panel display is blank:
Check that:
n
  the display hasn’t been turned off. Press the DIS 
button on the remote control.
No picture is produced:
Check that:
n
  your viewing device is turned on and switched to 
display your AVR300. Test by pressing the MENU 
button on the AVR300 or AVR300 remote and look for 
the AVR300 ‘Main Menu Screen 1’ displayed on your 
device.
n
  the correct video input is selected on the AVR300
n
  the video source is on, is operating normally, and is in 
‘play’ mode if appropriate.
The video source is different from the audio:
Check that:
n
  the video and audio inputs are correctly selected 
in ‘Main Menu Screen 1’. Press MENU, then change 
either the video or audio source by rst using the 
navigation
5
and
6 
buttons, then use the source 
buttons to select the correct input.
n
  the digital audio inputs and HQ video inputs are 
correctly assigned to their sources on the ‘Digital 
Settings’ page in the Set-up Menu.
There are bright edges or ‘ghosts’ on the picture:
Check that:
n
  the cables used for video connections are designed for 
that purpose (i.e., they are 75Ω coaxial cables).
n
  the ‘Sharpness’ control on your video display device is 
switched off or set near minimum.
There is no on screen display (OSD):
Check that:
n
  your video display device is connected to your AVR300 
correctly.
n
  the on-screen display has not been turned off on the 
‘Video Settings’ page in the Set-up Menu.
n
  if you are using a component display, check that the 
AVR300 is set for component video. See the ‘Basic 
Set-up’ section.
OSD Display is pink/red:
If a component video signal is fed into the AVR300 when 
the ‘HQ Video’ setting is set to RGB you will have a pink/red 
OSD.
To correct this you must set the ‘HQ Video’ line on the 
General Settings menu to ‘Component’.
No On-Screen Display (OSD) overlaid on video:
The AVR300 cannot overlay video onto progressive scan or 
HDTV signals. In this case, the AVR300 creates a full screen 
display with a black background for the menus and turns off 
the pop up messages.
No sound is produced:
Check that:
n
  the correct input has been selected.
n

‘MUTE’ is not displayed on the front panel display.
n
  your power amplier(s) (if any) are turned on and 
working correctly.
n
  you have assigned the digital input to the correct 
source button.
n
  the AVR300 is not in Stereo Direct mode with with only 
a digital signal supplied.
The sound is poor or distorted:
Check that:
n

are making a good connection. If necessary withdraw 
the cable from the connector and plug it back in again. 
(Turn the power off before doing this)
