hello guys do you have any idea why this happening?? the screen is okay no broken LCDits Chinese brand like Besat or Dansat
@nisoo7 could be a bad main board or a bad T-con board. In the case of this TV we will definitely need to see all the boards and how they interconnect. It would also help if you post an image of what the whole screen shows you. It looks like you have a thick white vertical stripe. That means your panel is not getting a signal on that tab. But we need to see all of it. Take some good pictures of the complete back of the TV and then each board. Post those with your QUESTION. Adding images to an existing question Of course, you have tried all different input sources already to make sure that they are all showing the same thing. Also try different cables HDMI Component etc.
