Troubleshooting

The software may be updated for improvement in
performance. The customer is responsible to ensure
the compatibility of their equipment with any LG
Electronics software. If needed, please consult with
LG Electronics and update new software versions
according to the guidance provided by LG Electronics.
• Cannot control the monitor 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 monitor turns off suddenly.
- Check the power control settings. The power
supply may be interrupted.
- Check if the auto-off function is activated on the
settings related time.

• Abnormal Display
- If the monitor feels cold to the touch, there may
be a small flicker when it is turned on. This is
normal; there is nothing wrong with monitor.
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 monitor'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 monitor. Those dots are deactivated pixels
and do not affect the performance and reliability
of the monitor.
- Displaying a still image for a prolonged period
of time may cause an image sticking. Avoid
displaying a fixed image on the monitor screen
for an extended length of time.
• Generated Sound
- Cracking noise A cracking noise that occurs
when watching or turning off the monitor 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.
