Screen issues, pictures and description attached.

@helpwithsamsung could be a bad main board (most likely) or a bad T-con board. Worst case scenario it s bad LCD driver board (unlikely). I would start by replacing the main board. Get it from a place that has a decent return policy (or a cheap used one) so you can return it if it does not resolve your issue. OF course, check all the ribbon cables and make sure they are properly seated etc. Specifically the ones on the T-con and main board. Always check for obviously damaged components as well. You can always post some pictures of what you find with your QUESTION. That way we can see what you see.Agregar imágenes a una pregunta existente
