ENGLISH

• Generated Sound

Cracking noise A cracking noise that occurs

when watching or turning off the TV is

generated by plastic thermal contraction due to

temperature and humidity. This noise is common

for products where thermal deformation is

required.

Electrical circuit humming/panel buzzing

A low level noise is generated from a high-

speed switching circuit, which supplies a large

amount of current to operate a product. It varies

depending upon the product. This generated

sound does not affect the performance and

reliability of the product.

• Take care not to touch the ventilation openings.

When watching the TV for a long period, the

ventilation openings may become hot. This does

not affect the performance of the product or

cause defects in the product.

• Do not install this product on a wall if it could be

exposed to oil or oil mist. This may damage the

product and cause it to fall.

• If the TV feels cold to the touch, there may

be a small flicker when it is turned on. This is

normal; there is nothing wrong with TV. Some

minute dot defects may be visible on the screen,

appearing as tiny red, green, or blue spots.

However, they have no adverse effect on the TV’s

performance. Avoid touching the LCD screen or

holding your finger(s) against it for long periods

of time. Doing so may produce some temporary

distortion effects on the screen.

• Displaying a still image for a prolonged period

of time may cause an image sticking. Avoid

displaying a fixed image on the TV screen for a

extended length of time.
