Any help would be appreciated. I'm not sure if i have t-con, main board, or panel issue?

More likely to be panel.
You need to open up the back and see if the T-CON, tab bonding boards are on the bottom edge of the LCD panel or not.
Did anyone spray the screen with cleaner to clean the screen?

were you inputting a signal during those tests.... the other side should have shown a picture.

Just the home screen that was shown in the original picture. That is kinda what lead me to believe it wasn't a panel issue. Thoughts?

So do you get picture just like in post #1 when both cables are back in place?

I had the same exact defect on a little older LG, it's a common issue on LG panels, the problem is on the source driver cof that began to slightly desolder, i have fixed it for some minutes but i had too much hurry to remount the bezel, the story is long, i ended cracking the cof due to shim mal positioned, its not easy when there is not a confortable plane of work. I think a better technique than mine can be used to fix it much faster and better with the use of a simple soldering iron stylus.

the other side should have shown a picture.

not on the LG..

NOTE: A COF is a chip! not the band that holds it.
