#1 TDSYSTEMS K55DLT6F override LED Driver protection

Hello everyone!

I have this TDSYSTEMS TV with MAIN CV9203H-A50, which sometimes turns on without any problems, and other times (most of the time), the LEDs flash for a second and then turn off, but the TV continues to work and the image is blank.

I need to override the LED protection for testing. Can anyone tell me how? I haven't found what the LED driver is. There are no components on the back of the main unit.

I found a post on another forum where someone was able to override it by replacing the PR115 resistor with a 2.7 ohm resistor and removing the SMD resistor marked in the photo. In my case, I tried it and it didn't work.

Any suggestions?

Is this correct?
The 8-pin chip is AS358M

Edit: I leave here another photo where the marks of the resistors can be seen better.
