LED BLINK CODES 

The blue and red LED lights on the TV (at the bottom of the TV) indicate the TV's status, as described below:  

Note:

 If the TV loses A/C power (e.g., a power outage occurs or the power cord is unplugged), when power is restored, the red

LED will blink while the TV is booting until the remote control is usable. This is normal and is not a sign of malfunction.
