Solution:
1. Try to change the program source. If there is no such problem in other sources, it is the source problem. This problem is commonly seen in some older programs, some older sources on the boundary will have some stray display, resulting in the emergence of the edge of the bright line, black edge, color bar and other phenomena.
2. If there are still bright lines on the edge of other film sources, please to the TV main interface or the TV RECOVERY interface for viewing. If there are bright lines and other things on any interface, it is suggested to after-sales for inspection.
Notes:
If a black edge appears on a connected box, please change the box Settings related to "images."
