My 58 in hisense tv has black blobs on the right edge of the screen, 4 lines going across the screen and recently started flashing white light
@jp082119 darn that is a broken LCD screen. There is no fix for it. The only thing you can do is replace the panel. Panels that size, if they are even available, cost more than a new TV, What I suggest is that you try to purchase a TV that is broken other than the screen and harvest the screen from that. OR you can try and remove the back cover from your TV and use the panel model number that is on a sticker on the back of that panel and try to find a good used one. The only other thing to do is to remove the boards from your TV and sell those separately. Then take the rest of the TV for recycling and invest in a new TV. Nothing here is good news but that is really the only thing you can do.
