*1 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 TOSHIBA dealer for service.

*2 If the display turns off 5 seconds after powering on and then the POWER/STANDBY indicator blinks, the power supply circuit, plasma display panel, or one or more fans have been damaged. If this happens, power off the display immediately and contact your dealer or authorized TOSHIBA Service Center.
