Repair Samsung Smart TV
(1/1)
Ghitza:
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!
