Possible Causes
• Check that the power plug is securely inserted into both the
AC INLET socket on the TV and the wall outlet, and that
the wall outlet is switched on.
• Check that power is available from the wall outlet by trying
another appliance or desk lamp from that same wall outlet.
• Ensure the TV power is ON (indicated by the green Power
indicator on the front of the TV)
• Try a different input source to check whether the source is
at fault.
• Check for mis-connection of cables or for wrong input
source.
• Make sure the antenna cable is properly connected.
• Change programs to confirm if the symptom is still
present.
Your TV antenna signal is being affected by interference from
automobiles, trains, high-voltage transmission lines, neon
signs or another sources of interference. Try redirecting or
relocating your antenna to reduce the affects of the
interference. If the antenna is exterior, have a suitable
qualified and experienced antenna specialist adjust the
antenna.
• Check whether all the picture adjustments have been
properly performed.
• Press Preset/yellow button
select a different picture mode.
Try selecting a different aspect ratio by pressing Aspect/
teletext size

on the remote control.
Ensure the TV's aspect ratio is correctly set to suit the image
source.
• Reduce the contrast setting.
• The DVD player output level is too high. Reduce the
output level and try again.
• The video signal has not been terminated properly
somewhere in the external equipment. Check the
connection and try again.
• Reduce the brightness level till the black areas of the picture
appear as black.
• The DVD player brightness level is too high. Reduce the
brightness level and try again.
