Question Samsung Smart TV UA46F6400 Picture problem

Nov 25, 2020
I bought this tv few years ago and it's been working perfectly but a few weeks back, the picture started doing some weird stuff which can be seen in attached photos. Half of the screen on the left side seems to be reflected and is really dark and sometimes very light. I opened up the tv from the back and disconnected the ribbon cables from the 2 green boards and reconnected them but that doesn't seem to solve the problem. Can anyone help?
I'll clean the boards with some isopropyl alcohol and let it dry and try again and post the update if the problem's still there or not.
