Is the black line a result of an impact on the television, or did it just appear?
If it's a black line, it may require either a panel replacement or the replacement of electronics, depending on the issue. If it's still brand new, you can either return it to your retailer, or we can send a service technician out to fix the problem. You can schedule that at 800-SAMSUNG.
My uncle was using the television to play Valkyrie Profile 2 on this brand new 52" HD television through RCA cables, and now there is a permanent black line running horizontally across the left side of the on screen display. Regardless of the source?
How can this be fixed?
