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.

Hello!
Van egy Samsung Slim Fit HD Ready 82cm televizió. Ha "hideg"-en be van kapcsolva akkor többször újraindul. Bekapcsol kb 3secre majd ki, ezt csinálja 2 percen keresztül. Régebben egyszer - kétszer kapcsolgatott ki be, de most már 2 percig csinálja után semmi baja.
Kis üzemelés után kikapcsolva és újra bekapcsolva teljesen jó, nem indulgat újra.
Üdv,
Zsolt

Hello everybody,
I could determine or measure the following with the device:
Device does not start anymore, stand-by LED lights red when device is plugged in and flashes red as soon as an IR command (key press) is sent via the remote control. Voltages of power supply STB 5V and signal LCD_TV_SUB_ON come from A-board. Power supply starts, supplies P15V and SUB1.1V, 1.5V, 1.8V, 3.3V, 5V, HDMI3.3V and USB5V are generated on the A-Board (stand for about 2.5 seconds). Then signal LCD_TV_SUB_ON goes low (voltages go away to STB 5V) and after about 2 seconds back to high (endless). What is missing is the voltage PNL12V which is switched on by PANEL_VCC_ON2. PANEL_VCC_ON2 always has a low signal and does not change its state. Power supply also provides for the 2.5 seconds the 24V for the backlight. Clocking of LCD_TV_SUB_ON starts immediately after plugging in the mains plug (also without IR command). SOS error code is not output. The over-voltage circuit in IC 5000 pin 7 also does not respond. Attached is the timing diagram from the technical training of Panasonic where I have drawn until when the boot process behaves normally.
In my opinion a mistake on the A-board? Does anyone have a tip?
greetings
Andi
