It's in the list of things that fail so why not? I really want to know why this is not an option.
Here's a video of another issue where it's just connections.
And no, it's not a black line there but the loss of a connection can cause so many effects that I love to remove the power and wiggle, unplug and plug cables as I've lost count of how many times that worked. If I do find it helps, watch the work this tech did to keep it from failing again.
This just started happening a few days ago.. a single black line spanning across ~2/3 of my screen horizontally has appeared, and will not go away. i've tried tapping on the back of the TV/squeezing the edges/pressing on the input panel in the back. i have not opened up the TV yet to lot at interior connectors/ribbon cables.. I bought this TV in 04/2014, so it's out of manufacturer's warranty :\ are there any suggestions other than checking the ribbon cables/interior connections?
The model number is : LC-60LE650U
