Most LGs I run into with this symptom turn out to have bad LED backlights. Usually in a dark room, plugging in and turning on the set you can see a momentary flash on the screen if they are the problem.
I did not see any "flash" of the logo or anything. I just get the power LED blink 3 times (red). I replaced the power supply with a new one - no change.
