Hi Sir, I have a Vitron 55 smart TV model: HTC 5568US that displays horizontal bars during turn on then the video dissappears as most of the screen goes dark. I noted that some ICs on the TCON board are heating. When I remove the right TCON to scalar board ribbon cable the tv displays a faded grayish picture on the left side. When I remove the left ribbon and leave the right only horintal bars display one the right side. Please help

I wonder if a thermal camera would work as well…

Many thanks for your comments and observations! I am always hesitant to touch components with my finger, especially when the boards are such.
