QLED Q9F - QE65Q9FAMLXXN - white picture balance problem

Can't Post

Hello,
I would like to ask for help in the following case:
I got to repair the QLED Q9F TV has a white balance problem like the movie - link -

In older Samung TV sets, it was enough to replace the AS15-U system or its derivatives.

however, I do not see the AS15-X IC on this board
I bought the above-mentioned eBay mainboard - but the effect remains - I'm afraid it could be a matrix driver.

however, the backlight works correctly according to me.
I am asking for advice and help in the repair.
Regards,
Majk
