@hotshot7777 for the 5 blink error the description is a TCON Error. The issues can be the LCD Panel, TCON, or the Inverter board. Let us know what is going on with your TV so we can try and verify this to be a possible T-con board error.

Once you remove the back cover from your TV (unplugged and no touching) Post some good pictures of your boards and the interconnect cables with your QUESTION. That way we can see what you see. Adding images to an existing question
