Static?? If I hover over the main board it shuts down

[chevellebbc@yahoo.com]

Hoping for some newbie help. I had a tv in the basement for years that needed diagnosis. Finally got to looking at it. First was a backlight issue. Power supply checked out and replaced the led set. Then when the main board plugged it the backlights shut off. So pulled the main board tested as many components as possible and didn't find the culprit. So sourced an eBay one for cheap hoping it was something correctable. But now with the timing board unplugged the tv will start with backlights and stay on. However if I touch the ribbon it'll attempt to shut down. Now if I even hover my hand above the main board ribbon it'll also attempt to shut down. Have a video trying to add a shareable link

Lets see a video of that hover shutdown thing, sounds fascinating.
