IMPORTANT SAFETY INSTRUCTIONS
 
y
Dot Defect
The Plasma or LCD panel is a high technology 
product with resolution of two million to six million 
pixels. In a very few cases, you could see fine dots 
on the screen while you’re viewing the TV. Those 
dots are deactivated pixels and do not affect the 
performance and reliability of the TV.
 
y
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 on the 
product. 
This generated sound does not affect the 
performance and reliability of the product.
 
y
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.
 
y
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.
Preventing “Image burn” or “Burn-in” on your TV 
screen
 
y
If a fixed image displays on the TV screen for a long 
period of time, it will be imprinted and become a 
permanent disfigurement on the screen. This is 
“image burn” or “burn-in” and not covered by the 
warranty.
 
y
If the aspect ratio of the TV is set to 4:3 for a 
long period of time, image burn may occur on the 
letterboxed area of the screen.
 
y
Avoid displaying a fixed image on the TV screen for 
a long period of time (2 or more hours for LCD, 1 
or more hours for the Plasma TV) to prevent image 
burn.
