UE55KU6179U No Backlight and Powercycling

Post by HaukeM » Fri Apr 12, 2019 9:40 am

Hello guys,
My Samsung UE55KU6179U does not turn on. When I plug it in the outlet, the Standby LED shortly blinks and the TV tries to start. The backlight stays off, but with a flashlight I can see, that the SMART TV logo is shown very shortly on the screen. Then the TV shuts down and tries to start again.

I already tried the EEPROM reset by shorting I2C data signals to ground. When I did this, the standby LED stopped blinking. It seemed that the TV even responded to the remote. But there was still no picture.
I also checked the backlight LEDs, they are all fine.

Do you have any idea? The Mainboard model is: BN41-02528A

Is there any UART port for boot diagnose?

Thanks!

I managed to repair my TV. The PSU was the problem.
