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 Timer Power Off / Sleep Timer
feature is activated in the Timers settings.
- 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.
