Dew formed on or inside
the LED-backlit display.

cold room to a hot room temperature. Do not turn ON the LED-backlit
display, wait for the dew condensation to disappear.

glass surface.
• This happens due to humid weather conditions. This is a normal
occurrence. The mist will disappear after a few days or as soon as the
weather stabilizes.

static image appear on the
screen.
• Turn off the LED-backlit display for extended periods of time.
• Use a screen saver or a black and white image and run it for extended
periods of time.
