Chapter 10: Troubleshooting

LED indications

The green and red LEDs on the TV front touchpad (to the left of the POWER button) indicate the TV’s status, as described below.

Red ON (solid) and Green OFF = The TV power cord is plugged in.

Green ON (solid) and Red OFF = A recording is in progress while the TV is OFF.

Red ON (solid) and Green ON (solid) = A recording is in progress while the TV is ON.

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