@markturnip it sort of is the panel. What you have is a failed Gate driver. Those are responsible for the horizontal part of the images. This could be an issue with the driver boards (those are the long skinny boards that connect to the panel via plastic film ribbons) or a failed COF itself. Of course, you can always take it further apart and check those things out. Sometimes they can be repaired by applying some external pressure to close the contacts. Most of the time it's a loss for the DIYer since we do nto have the proper machinery to repair those.
Once you have it further dismantled, post some good pictures of those ribbons and let's see if we can narrow it down [guide|21499]
