Hello guys,
I have a LG TV OLED55C9PLA which does not start at all. 
The only sign that is alive is some vertical colored lines on the right side of the screen that are appeared at the beginning and that's it. After that black screen.
I have uploaded a short video (more than 3Mb) to understand better what I mean.

If you have any experience from such problem please help me to fix it.
Thanks in advance.
Theo

Hello Theo!
This problem is the display defect. Vertical line controller is bad. This defect can not repair, need change to new one display.

Hi Laszlo,
T-Con board is a separate module
See this for example which is the same model.

Dear Theo!
For 15 years, I was a service engineer at Philis' central service in Hungary. I also repaired LG devices in parallel. Every year I attended a service course for both Philis and LG devices. All OLED TV displays are configured at the factory for the T-CON panel. The white balance is set individually for all the LEDs of the display. Even if you find a disassembled T-CON panel on the Internet, it will not be suitable for your display. But you can try, but it won't be good. The reason why the vertical stripes appear on the display is that the matrix circuit is integrated on the LVDS connector cable of the display.
