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.

LED drivers - link here -

however, the backlight works correctly according to me.

I am asking for advice and help in the repair.

Regards,

Majk
