    Thats not a dead pixel, I've seen this on laptops and I think its related to the video input in the tv that goes into the actual lcd panel. It'll need to be opened up to check the cable is secure and not damaged.

    no it's not dead pixels, they would be random

    By sending the appropiate signal to a row and a column driver you can turn/off a particular pixel. So either mechanical damage breaking the electrical connection or a problem with the chip driving that column.

    or could be something weird too.
