@travisgray93425 those long skinny boards are your LCD driver boards. You are right, those ribbon cables connect right to your :LCD those boards are not replaceable by a DIY'er and are considered part of the panel. The second picture shows the LED driver board (where the screwdriver points to). That is basically what provides the power to light up your screen.
Those ribbon cables in picture number 4 look rough. I would actually consider replacing them. If I understand your narrative correctly, it works okay until you connect the left driver board. Then it all goes downhill. If so, you know the issue is on the Left driver board. It looks like there are small ribbon cables that connect the driver boards. Those can tear as well and are known to cause issues like the one you describe. If you can, post a couple more pictures of the driver boards and let us know if there are 2,4 or 6. Also, one more picture of the board where those two black ribbon cables originate from. I predict that you have no separate T-con board but your T-con circuitry is integrated into the main board.
A tape-off may actually fix this (85% chance)

@travisgray93425 not a legend just an old dude trying to safe the world :-) You can't use a multimeter for those ribbon cables since they are data lines. We would need an oscilloscope and the proper information about what data goes over those lines.

Check the flex cables that daisy chain the driver boards. Those love to tear and shorten out the data lines as well. Do not forget to clean the inside of all of the the connectors. Use either some +90% isopropyl alcohol; or some non-conductive contact cleaner on the one that you know is trouble already.

A tape off refers to blocking the signal on the faulty data lines with a strip of tape. It's not an exact science and works about 85% of the time. It's time consuming since you would have to tape off the data lines on the side that is known to give you trouble (left in your case). Check the YT videos https://www.youtube.com/watch?v=pfrRhw7-ZII&t=4s and https://www.youtube.com/watch?v=atNmhu7HMj0&t=1131s for an idea about the Tape-off
