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.)

Have you not performed an operation for about two hours after the TV was switched on by the ON TIMER function? (see page 11.) If you don’t perform an operation within about two hours, the TV is automatically switched off for safety.

Poor picture

Press the COLOUR SYSTEM button to select another colour system. (see page 8.)

Adjust the picture settings. (see page 12.)

Set the Picture mode to STANDARD. (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.

The TV turns on suddenly

The TV channel changes suddenly

Is the ON TIMER function set to operate? (see page 11.)
