vertical lines all over tv, I replaced tcon board same issue, any ideas what could be causing this? model samsung un60h6203afxzc
brian pereira this could be a cabling issues. Verify that your cables to and from the T-con board are properly seated and in good condition (no tears etc.). After that you are somewhat stuck between a panel (driver) issue and a main board issue. Post some images of what your screen displays with your question. That will allow us to see what you see. Use this guide Adding images to an existing question Update (10/11/2017) brian pereira not sure which orientation your picture was taken but those look like horizontal stripes. Horizontal lines are never caused by t-con board issues. Those are caused by faulty gate drivers which are part of your panel. Of course you also want to make sure that all your cables are properly connected and that the connectors are in good order. Sometimes you can eliminate the lines by pushing on the ribbon cables that connect the LCD driver board to the actual panel. See if that makes a difference.
Broken Lcd or bad connection between cables
