*1 Overheat protector
If the display becomes too hot, the overheat protector will be activated and the display will be turned off. If this happens, turn off the power to the display
and unplug the power cord. If the room where the display is installed is particularly hot, move the display to a cooler location and wait for the display to
cool for 60 minutes. If the problem persists, contact your dealer.
*2 In the following case, power off the display immediately and contact your dealer or authorized Service Center.
The display turns off 5 seconds after powering on and then the POWER/STANDBY indicator blinks. It indicates that the power supply circuit, plasma
display panel, temperature sensor, or one or more fans have been damaged.
