Troubleshooting
Cannot control the TV with the remote control.
•  Check if anything such as tape has been placed over the receiver.
•  Check if there is any obstacle between the product and the remote 
control.
•  Replace the batteries with new fresh ones.
No image display and no sound is produced.
•  Check if the product is turned on. 
•  Check if the power cord is connected to a wall outlet.
•  Check if there is a problem in the wall outlet by connecting other 
products.
The TV turns off suddenly.
•  Check the power control settings. The power supply may be 
interrupted.
•  Check if the auto-off function is activated in the settings menu.
•  If there is no signal while the TV is on, the TV will turn off 
automatically after 15 minutes of inactivity.
Abnormal Display
•  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.
•  This panel is an advanced product that contains millions of 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.
•  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.
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.
•  When cleaning the product, be careful not to allow any 
liquid or foreign objects to enter the gap between the 
upper, left or right side of the panel and the guide panel, 
(Depending upon model). 
•  Make sure to wring any excess water or cleaner from the 
cloth.
•  Do not spray water or cleaner directly onto the TV screen.
•  Make sure to spray just enough of water or cleaner onto a 
dry cloth to wipe the screen.
