Before Calling Service

Items to Verify and Actions to follow
• 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.
• Verify 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.
• Verify 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.
• Verify the Closed Captions control. Some TEXT modes could block the
screen.
• Verify if you selected the correct AV source.
• Your TV has a protective mode in case there is too much heat build-up.
Verify the clearance around the vents of the device to be certain there are
no blocking walls or cabinets which would limit the air flow.
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.
Note: 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.
• Verify if the source complies with a supported code.
• Increase the VOLUME.
• Verify that the TV is not muted, press the
control.
• When no signal is detected, the TV automatically switches off the sound.
This is proper operation and does not indicate a malfunction.
• Adjust the contrast, color, tint and brightness setting.
• Select Reset AV settings in the Installation menu.
• Verify the antenna connection.
• Verify 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 > 240".
• You can still use the buttons at the right side of your TV.
• Verify if the remote control is in the correct mode.
• 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 50".
