Trouble Shooting Tips

Symptoms

Items to Check and Actions to follow

“Ghost” or double 
images

• This may be caused by obstruction to the antenna due to high rise buildings or hills.
  Using a highly directional antenna may improve the picture.

No power

• Check that the TV’s AC power cord is plugged into the mains socket.
• Unplug the television, wait for 60 seconds. Then re-insert plug into the mains socket  
  and turn on the television again.

No picture

• Check antenna connections at the bottom of the TV to see if they are properly connected to the TV.
• Possible broadcast station trouble. Try another channel.
• Adjust the contrast and brightness settings. Try another auto picture setting.
• Check the Closed Captions control. Some TEXT modes could block the screen.
• Check if you selected the correct AV source.

No picture and power 
switched on

• Your TV has a protective mode in case there is too much heat build-up. Check the  
  clearance around the vents of the device to be certain there are no blocking walls or  
  cabinets which would limit the air flow.

Picture position  
adjustment

When displaying a High Definition signal from the YPbPr inputs or HDMI input, if necessary, you can  
adjust the picture position to the center of the screen with the cursor left/right or up/down buttons on 
the remote control. This may be needed due to slight differences in output signals from different brands 
and types of HD sources boxes.  

Notes: Most High Definition receiver boxes also have picture-positioning controls in their menu  
systems. If the TV cursor controls run out of range before the picture is correctly positioned, the  
receiver box controls will need to be adjusted.

No photo, music or 
video play or in poor 
quality only

• Check if the source complies with a supported code.

No sound

• Increase the VOLUME.
• Check that the TV is not muted, press the MUTE button on the remote control.
• When no signal is detected, the TV automatically switches off the sound. This is proper  
  operation and does not indicate a malfunction.

Good sound but poor 
color or no picture

• Adjust the contrast, color, tint and brightness setting. Try another auto picture setting.

Snowish picture and 

noise

• Check the antenna connection.

Television not  
responding to  
remote control

• Check whether the batteries are working. Replace if necessary.
• Clean the remote control sensor lens on the monitor.
• Operating range between TV and the remote control should not be more than approximately twenty feet.
• You can still use the buttons on the right side of your TV.
• Check if the remote control is in the correct mode.

Control of accessory 
devices

• The infrared signals of the screen may influence the reception sensibility of other peripherals Solution:  
  replace the batteries of the remote control of other devices. E.g. keep away a wireless headphone from   
  within a radius of approximately four feet.

The software will not 
install

Possibly the operating system is wrong.  
Go to www.usasupport.magnavox.com to see which operating systems are supported.

Standby

Your TV consumes energy less than 1w in the standby mode. 

After improper  
shutdown

If your TV has been shutdown in an improper way (e.g. power drop, power cord plug out), starting up the 
TV again will take a longer time than usual.
