Troubleshooting

If there is no picture or the TV does not operate normally, make sure the problem isn’t 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 12.)

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

12.)

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

12.)

Poor sound

• Adjust the sound settings. (see page 15.)

Poor picture

• Adjust the picture settings. (see page 15.)

• 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 13.)

• If noise (snow) totally blocks out the picture,
check the following.

- Have the TV and antenna been connected prop

erly?

- Has the antenna cable been damaged?

- Is the antenna pointing in the right direction?

- Is the antenna itself faulty?

• If the TV or antenna 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 antenna suffer interference from
signals reflecting from mountains or buildings,
double-pictures (ghosting) will occur. Change
the antenna’s direction or replace it with an
antenna 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 colored. When
the image disappears from the screen, the
unnatural colors will also disappear.

The picture is tilted

< AV-29L31 and AV-29L31B only >

• A picture may be tilted due to the influence of
the earth’s magnetism. In this case, use the PIC­TURE TILT function to adjust the tilt. (see page

11.)

Screen is 80% black

• Press the CLOSED CAPTION button to select
“OFF”. (see page 8.)
