Report "I have an LG 42LN5200 that I asked about earlier. To recap, the screen went dark but there was still sound. Flashlight test shows images. Thought it was the LEDs, bought an LED tester and they all lit up. Decided to plug it back in to see what it would do, and now after being plugged in all the lights flash every 4 seconds. And I hadn't pushed the power button. Any ideas?"
