Troubleshooting
If there is no picture or the TV does not operate normally, make sure the problem isnt due to
the reasons indicated below.
If the problem persists even after taking the measures indicated, please contact a service
technician.
Cannot turn the TV on
Press the Main power button on the TV.
Connect the power cord to the AC outlet.
The screen turns blue
Is the BLUE BACK function 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 9.)
Is the AUTO SHUTOFF function on? (see page
15.)
Poor sound
Press the SOUND SYSTEM button to select an-
other sound system. (see page 8.)
Adjust the sound settings. (see page 16.)
< LS series only >
If there is noise during mono sound output,
press the button to select MONO.
(see page 9.)
Poor picture
Press the COLOUR SYSTEM button to select an-
other colour system. (see page 8.)
Adjust the picture settings. (see page 16.)
Is a component signal output device, such as a
DVD player, connected correctly? (see page 5.)
Is the VIDEO-2 SET function setting correct? (see
page 16.)
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 aerials 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.
The picture is tilted
< AV-29 series and AV-34 series only >
A picture may be tilted due to the influence of
the earths magnetism. In this case, use the PIC-
TURE TILT function to adjust the tilt. (see page
14.)
