Obstacle in the way.
On the equipment feeding the TV choose the correct
output aspect ratio such as 4:3 or 16:9 to match the
TV. On digital equipment you might choose 1280 x
960 pixels to match 4:3 screens or
1280 x 768 pixels to match 16:9 screens.
Put other equipment on stand-by to see if the
interference stops: change the output frequency of
the equipment that is causing interference(see its
instructions). Get higher quality cable.
Get your aerial system checked.
Increase the brightness and contrast settings.
As for 'Snowy picture' and 'Ghosts'
Press the AV button to select the AV input which

What to do
Make sure it is not a general power cut.
Check the power switches on the television and at the
power outlet. Check the fuse or circuit breaker at your main
fuse box. Look for a possible cause of failure before you
replace or re-set it. Disconnect power supply, wait five
minutes and try front panel STANDBY/ON. If still no good,
disconnect power supply and assume the unit is faulty.
Switch off mains power and wait 10 minutes before trying
again. (Leave the TV unplugged and call a service
engineer if this does not work.)
Insert new batteries
Remove any objects and aim from straight in front of the
remote sensor with a clear line of sight.
