The right half of my 65” tv is flickering/ghosting

The right Half of my 65inch of my tv is ghosting/flickering with horizontal and vertical lines. The bottom right of my tv is almost black too. Sometimes when I use the tv it works okay-ish and the ghosting/flickering is reduced but is still visible. I know that the screen isn’t broken because when the tv boots it is perfectly fine (no lines, flickering/ghosting , or dark spots) because it boots with the logo on the white screen which is normal. But after it boots the screen turns off for a second(which is normal) and comes back on to finish booting, and the screen had the same logo on white background but with all of the problems mentioned. I’ve opened up the tv and cleaned the ribbon connectors that go to the display panel but that didn’t go anything. I’ve also tried switching tv inputs with no success.
