Identifying backlight resistors, power supply is a BN44-00852

[unimatrix93]

Dear forum, I would like to ask some help identifying the backlight circuits resistors to limit the ampere to the backlight leds.
The power supply is a BN44-00852 and I want to decrease the backlight to increase the lifetime of the LEDs.
The TV is pretty much always on, used for CCTV cameras.

I suspecting R9838 -> R9841 resistors but I'm not sure. Thanks in advance!

R9842 - Increase resistance.

Thank you very much. The video is also very useful.

How can I identify these kind of resistors in the future?

It all depends on what backlight driver is installed in the TV.
