TCL TV - Vertical lines left side after LED backlight replacement

I did a 12 strip LED backlight replacement on my TCL 65S401. It went great - in that aspect haha. However, now i have a section of vertical lines on the left side.

First set of lines is 10 inches towards center from the left side. The set of lines is 3/8 wide of alternating blue pixel lines and black pixel lines, running on top of the menu screen. Roughly 1/2 inch to right of that is two single pixel blue lines roughly 1/8 inch apart and running under the menu screen. Any help would be very appreciated. Ive tried disconnecting and reconnecting all the ribbon cables and it didn't help.

@timmy1892 could be a T-con board/main board error as well as LCD driver board error. We would need to see what all of those look like. Check the ribbon cables that enter your LCD and originate at the LCD driver board. If you push down on those do the lines on your TV change? Adicionar imagens a uma pergunta já existente

Messing with the ribbon cables doesnt do anything, disconnecting/reconnecting and cleaned with alcohol didnt fix. Im wondering if i flexed the screen juuust a bit too much. The Led backlights went out so I bought a replacement pack from shop jimmy. The backlight is fixed, but whatever i did caused this line. I was willing to try the 75$ fix, oh well, at the end of the day new tvs are cheap.
