It could be that or a board, sometimes a connection. The one thing my TV repair friends tell me is it's rarely the same thing from set to set. So get estimates.

I have a Toshiba 55L6200U (bought in September 2012). Two days ago, after a restart to bring back the sound that I had just lost in my wireless headphones, lines appeared (vertical and horizontal).
Lines are in a cluster, about an inch wide. Horizontal lines are located at the bottom and vertical lines are located about a quarter screen from the left
Where the two clusters meet, there's a small "explosion" of pixels on the screen, just like a rock hit a car windshield.
Am I necessarily looking at replacing the LED panel? Or could it be something else?
Thank you.
