I have a screen full of colorful vertical lines on my screen. Samsung UN55B7000WFXZA

Hey gang, this all started with a ghost picture, was like having two pictures offset on my tv, I scouted forums, and decided to try and reset the ribbon cables on the t-con board and even tried putting a piece of tape, yada yada, nothing worked. Now I have a screen full of colored vertical lines. I cant even get the ghost picture back up. I bought a new t-con board, the same lines still there. I cant see the menu, or any display, just these lines. I can change the source with the remote, it changes some brightness between changes but no picture change.

Any of you guys have an idea of whats wrong?

This could be a tab bond problem. Open the tv and search for the tabs on the panel and apply some pressure and see if it changes.

You sure the T-con is the right T-con? For example old one is V4 and you bought a V6.

Looks like Lcd panel failure to me, try unplugging one side of the screen to see if the other comes back. If not tear it apart to the panel and check the tab bond drivers one is probably on fire and shorted.

If 1 tab is failing it causes lines on 1 side of the screen. ( below the tab ).
This is either a bad connection between the T-con and the cable OR a bad panel. Temporarily fixable with applying some pressure on it.

Watch this, a shorted driver Ic can cause the whole screen to fail as it overloads the Tcon causing the whole screen to glitch not just one side if there is a loose tab bond could cause one side or lines on certain areas:

I visually inspected all of the tabs on the edge of the panel and didn't see anything that looked burned or loose, I didnt try pushing on them with tv on though. It went from ghost image to this with me messing with the ribbon cables that attach to the tcon board... I purchased the t-con board from a seller on ebay in china, took almost a month to get here. my board is a 02719k and the one sent to me is a 02852d. The seller said they are compatable.. the screen looks a little different when I put in the new board, instead of smooth vertical lines, it has some horizontal looking lines. Ive attached pictures of the screen with the old board and new board...

My question for you guru's, if it was a tab, would the entire screen go colored lines like this, wouldn't only a portion of it? Is there anything else that could do this?

I think reeceyburger already provided you with the "evidence" that it is possible / probable. As the video indicated, try touching the tab driver chip on each flex tab cable to see if you feel any difference... that's likely the "tell".
