LG 49LB5550 3 inch vertical stripe

[bcgrafx]

After changing the LED strips, I now have a 3" vertical magenta stripper. Did I need to the LCD or is something wrong with a board? All other functions of TV seem to work fine. I have reseated all cables with no change. I still need to try swapping the two tcon ribbon cables and see if the stripe moves.

I'd say you've probs damaged the COF at some point.

"I still need to try swapping the two tcon ribbon cables ...." NO! Never do it, different cables hav different signals, you will detroy panel or tcon.. there's a probability you have broke the glass..
