Flickering TV screen, everything else works!

Hello,

I am having a problem with my LG LCD television (model: 60LB650V). Purchased in December 2014.

The problem: when I turn on the screen, it flickers (1 flicker then another weaker one each time) regularly every 2 seconds or so without stopping.

However, everything else works perfectly: the sound, the remote control responds to the functions in the menus...

I read on forums that it could be a screen that is "pumping"! The issue is that the capacitors (on the power supply) appear to be in perfect condition (no swelling, no visible marks...). I also read that capacitors have a limited lifespan.

Moreover, I noticed that the antenna input socket was slightly leaking on its own... but I don't see the connection.

    Hello
    I noticed that the antenna input was slightly leaking onto itself..
    Maybe it’s unrelated, but it’s not normal either
    We need to find out where this leaking is coming from, which makes me think of a battery that’s been left too long in a device
    (the leaking battery syndrome)
    So on the TV, not a battery, but probably a capacitor or some other electrical component

      I confirm as well. I was surprised, it also stuck on the plastic frame that protects the card with the infrared... I need to check what could be leaking like that and especially understand why the screen flickers while operating normally (sound...).
