Hello,
I have my TV model UE50KU6070 which I am trying to repair.
BN41-02528A / BN94-10800C motherboard.
If I disconnect the motherboard from the power board, the backlight works. When the motherboard is connected the backlight works but the screen remains black.
When I plug the TV into the electrical outlet, the standby LED lights up but no reaction to an attempt to start it with the remote control for about 1 minute. During this minute the TV consumes about 20W.
After one minute the consumption drops to 0W and the TV can turn on with the remote control but the screen remains black. All voltages on the motherboard are correct.
The TV turns off with the remote control but you have to wait about 1 minute before restarting it again. Sometimes at startup the screen displays "Samsung Smart TV" for 1 second before going black.
In fact, in addition to the black screen, it is as if the TV was extremely slow.
The behavior is the same if I disconnect the two LVDS cables.
Do you have an idea of the problem and do you think that the motherboard is repairable for example by reprogramming the memory?
Thank you in advance for your help.
