Cannot turn the TV on

(see page 15.)
Remote control inoperable
• Replace the batteries. (see page 3.)
Buttons on front of the TV do not
work
• Switch the CHILD LOCK function off.
(see page 15.)
TV does not respond immediately
• Press the main power button on the TV to
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.
The TV turns off suddenly
• Is the OFF TIMER function set to operate?
(see page 10.)
• Is the AUTO SHUTOFF function on?
(see page 15.)
• Have you not performed an operation for
about two hours after the TV was switched
on by the ON TIMER function? (see page 14.)
If you don’t perform an operation within
about two hours, the TV is automatically
switched off for safety.
Poor sound

(see page 8.)
• 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.
