    Thank you so much ….After waiting countless hours on the phone with Geek
    Squad, Samsung and a score of repair services, “expert” in Samsung Repairs,
    I decided to go with your fix, mostly out of frustration. 1/2 hour later,
    up and running and so far, so good…. My 55″ back in operation….However
    I will say a small prayer every day, as a disbeliever who has found a
    revelation, of sorts.

    Thanks so much for posting this. I was inspecting mine for the cap issue
    and was dismayed that I didn’t find anything wrong. Then I saw your video
    and removed the board and observed identical damage at the same terminal. A
    quick re-solder of all the heavy component locations and it ran for
    multiple hours without issue. Spot on video!

    @mirmarx1 Great, you’re welcome. Guess this can be considered a somewhat
    common problem.

    @stgubala Excellent!! Glad it helped, this is why I posted the video, to
    help out others if they had the same problem.

    I have the same symptoms on the exact same 40″ Samsung TV and I’m convinced
    that you identified the problem for me. I will try to get a soldering gun
    to fix any broken joints, but I am worried about being able to locate the
    proper terminal when I remove the board. Any suggestions about how I might
    do so? Can you superimpose an arrow or two in your video regarding the
    location of the joints? Thanks for your effort!!
