i have the sames TV. It powers up, but no picture, only flashing lights on the bottom front of TV. It starts trying to power up the LED and a single green on the right a few times, then all 3 blink a few times including the red light. I have a feeling it's the LED engine. have you heard of these symptoms for only a LED itself. I recently had to replace the fan on back of the red LED before this happened. If anyone has any info, i would greatly appreciate.
