    my TV have always been hooked up to my computer since i got it, never gave me any prob but just about few hrs ago i randomly started to have a strip of red area on the far right of the screen.
    it goes in and out when i turn the tv off for a few min and then turn it back on it it'll not show for a sec then i'll come back.
    and it only shows in gray any one know why is that?
    here is a video of it.

    That's a bad cable or connection somewhere, bad tv or some software/driver mess that Ive never seen before.
    A dead or stuck pixel is smaller then a period .

    A horizontal or vertical strip of pixels that differs from the rest of the screen content usually means a defective LCD panel (likely a solder joint for that row of pixels cracked or is faulty). Unfortunately it happens to a lot of the cheaper LCD TVs, sometimes within a few months or even a few days. Dead pixels mean they stay black, and stuck pixels continuously display one color, but those typically appear individually or in small clusters on defective panels. Whole lines malfunctioning is a much bigger problem.

    here is a picture. and seems like the LCD panel itself looks fine i tried different colors and nothing shows up so pretty sure it's not dead pixel but just unsure which board is the one that's starting to going out here. i have a feeling it's either the A-board or the LCD controller

    Untrue. I've seen how they appeared only once and disappeared right after reboot and never occurred again. Strip of pixels <> dead pixels
