Vertical Lines after replacing LED light strips

I initially had some dark areas on my Vizio M70-D3. I researched and learned that I could replace the LED light strips. Went through all the work and updated all the strips. Got the TV all put back together and was excited to see my handy work! Display now looks nice and bright but I have a small area of the display has multiple colors of vertical lines going through it.

Researched that problem and several folks said to replace the t-con board. Did that and same verticle lines.

Anybody got any ideas before this one goes to the recycling shop? Thank you in advance!

I have seen this issue before from when another technician was still learning how to do these repairs. If you have already replaced the t-con board and verified that all of your connections are good, I don’t have great news. Typically what I have seen is one of the ribbon cabless running into the lcd gets caught on something when moving it around and it tears the cable. This typically requires LCD replacement and I have unfortunately never seen a scenario where it makes sense to do so, typically due to parts availability.
