I inherited a Samsung UA50KU6000SXNZ for free as it has a black vertical line about 10cm wide on all inputs. I'm 95% sure the issue is the Tcon board.
A genuine replacement Tcon part no BN94-10800X is around $400 ex Samsung NZ.
Shopjimmy.com has similar boards but with an 'A' or 'Z' suffix rather than the X, and I note in the pictures the satellite connector is missing which does not bother me, see here: https://www.shopjimmy.com/catalogsearch/result/?q=BN94-10800
I can land one of these for under $100
What are my chances of the cheaper boards working ok?
