LG 43” tv works with slight fault (Gleedless (S12))

Hi I have a 43” tv which I can gift.
It has a black patch in the top of the screen which flickers while watching. It has been like this since December, we have been watching tv with it like this and I think we got used to it after a while.
Collection tonight from Gleadless Avenue would be ideal don’t think I’ll be short of offers.
