How To Fix SAMSUNG TV Screen Flickering and ON & OFF || TV Display Problems & Repair

I have a Samsung LCD TV and It’s having weird Screen flicking issues. (Screen On & Off Issues) The colors are saturated and when the images on the display move they get blurred (video below); (Screen Flickering) it’s on every source. The TV is no longer under warranty so I’ve begun taking it apart. I changed some capacitors from the power supply hoping it was a filter problem but no luck. I’m thinking it could be the Mainboard or possibly the T-conn board. I’d hate to buy one and it ends up being something else. Also, could it be the inverters? Anyone had any experience with this problem? What ended up being the problem?

    Our Samsung smart tv has a flicker and dimming on the bottom half of the screen. On every source. Always there. Anyone else have this issue and if so did you find a solution?

    Hello Guys!

    I have a problem with my old samsung LE40M86BDX Tv.
    Basically every black color on the screen went blue.
    Sometimes I can see a rainbow line horizontal.
