I have been very happy with this set for a year now, however last night when the TV was on standby, I noticed the LED blink three times. At first I wasn't sure, but my wife confirmed she saw it also. My Pioneer Freeview box was on at the time but nothing else. When it blinked it blinked red/ green, red/green and again, not just red. The TV has not done it since and everything is as it should be. Any ideas anyone?
