Hello guys, I do need the help of the masters from this forum. I have this samsung smart TV model UE40JU6550UXZG and another internal SN CY-WJ040HGLV3H. It has NO backlight and NO image. I have repaired an old Toshiba LCD TV without backlight but there was image. The problem was from a LED bar strip. With this one I was thinking it is the same issue and I have completely disassembled the TV and I have checked all the LED bars and all are OK. After this, I have assembled back the LCD and the related components. When the blue board is connected to the yellow board, the TV starts but without backlight. If I remove that flex from the red curve, the backlight starts when I power on the TV. The yellow board I understood it is the T-CON board. It is possible to be only that the problem? Is there any way to check it to be sure? On the tcon board there Ive made a purple rectangle and there is a coil that goes into a small ic and the other side of the coil it seems it is connected to GND or it is a short circuit on that side? With all the flatcables connected between the boards and with that coil removed, the TV starts with backlight but without image. I really appreciate any help and ideas to solve this problem. Kind Regards! |

No idea related to this problem guys? I don't know for sure if I can order that tcon board or not. Maybe someone has already encountered this problem. Thanks in advance! |
