turn off the main power. Press the main
power button again to turn on the TV. If the
TV returns to a normal state, operation is
normal.

• If noise (snow) totally blocks out the
picture, check the following.
- Have the TV and aerial been connected
properly?
- Has the aerial cable been damaged?
- Is the aerial pointing in the right direction?
- Is the aerial itself faulty?
• If the TV or aerial suffer interference from
other equipment, stripes or noise may
appear in the picture. Move any equipment
which can cause interference away from the
TV.
• If the TV or aerial suffer interference from
signals reflecting from mountains or
buildings, double-pictures (ghosting) will
occur. Change the aerial’s direction or
replace it with an aerial with better
directionality.
• When a white and bright still image (such
as a white dress) is displayed on the screen,
the white part may look as if it is coloured.
When the image disappears from the screen,
the unnatural colours will also disappear.
