    Samsung UN50TU8000FXZC shows thin horizontal green line when warm

    Hi to all,

    I was given this TV, an entry-level 4K 50" set. Some have criticized its lack of contrast and relatively poor colour rendering, but for my needs, it's very decent.

    I reset everything to factory settings, but this line keeps on fading in and out when watching a streaming channel from the Tizen firmware. Interestingly, it only happens when TV is warm, after about 1h45 of it being turned on.

    Watching a movie from an external source doesn't trigger the line as easily (needs 2 hours), and from a normal viewing distance, is hardly noticeable. It is faint, but knowing it's here annoys me.

    I added a short yellow dash to help locate the green line.

    What could be causing this artifact?

    ViewSonic Pf815 (branded as P225f) Horizontal Deflection Issues - Running out of Ideas
    by rstrube
    Note: apologies I initially posted this request for help in the wrong forum! I am reposting it here and will take down the original posting.

    Hi Everyone,

    I've been working on repairing this beautiful CRT monitor off and on for the past several months and I'm really at a loss for what might be causing the problem.

    Unlike other common Horizontal Deflection issues which result in a steady vertical line, when I turn the monitor on, there is a pulsing (somewhat segmented) vertical line. I've attached a photo that shows the issue (difficult to capture without video)....
