LED indications
The yellow and blue LED lights on the TV (at the bottom center of the TV) indicate the TV’s status, as described below:
• Blue ON (solid) and Yellow OFF = The TV power cord is plugged in.
• Yellow ON (solid) and Blue OFF = A recording is in progress while the TV is OFF.
• Blue ON (solid) and Yellow ON (solid) = A recording is in progress while the TV is ON.
• Yellow and/or Blue blinking (see table 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 yellow LED will blink
while the TV is booting until the remote control is usable. This is normal and is not a sign of malfunction.
