Screen fades to black after a few seconds, reboots.

"Hey good people of this forum!
My 2019 q60r samsung started doing this after turning it on one morning. The screen appears to work just fine for a few seconds, the logo shows up, then it fades to pitch black after a few seconds. I can even access the menu just to see it go away immediately. 2 blinks on the red LED, rinse and repeat. Already replaced the PSU board, same result. Now I am about to send the main board to a place where they can diagnose it since no damage is visible. Any ideas before I go on a “rip me off” tour with samsung?
Thanks in advance!"

Lázár Gergely the fading is usually caused by either a failed T-con board or the LCD driver board. Of course check all of your LVDS cables. After that you need to check the voltage on VGH, VGL, VDA and VDD. If those voltages are low you need to check your cables coming from the main board as well as the main board itself. Should the voltages be ok you need to check the LCD driver board on the panel. None of this is simple…..Let us know what you find out when your Main board comes back.
