Lg 42LB5600 burns LED backlight repeatedly

Hello people, I have this TV in the workshop, which I repair (I change the burned LEDs), but after a few months it returns for the same fault.
I've been reading about lowering the brightness, but since I don't have the source diagram, I don't know what resistance to change in the CS leg.
In pin 2 (STB) of the BD9486F driver I have 2.83 volt.
Did any of you happen to them and could you solve this problem?
regards

Hi
I pass you a link here you have everything and a very good video.
Let me know how it went. It is a common problem that happens after the year by placing the backlight at maximum contrast and very high brightness.
In the case of this TV the board says 208 volts 235 volts. It has 32 led of 6 volts, they are working to the maximum and they are going to burn.
I hope it serves you.
