In the above TV, the 13V voltage reaches the T-Con HV320WX2-261_X-PCB-X0.0
There is 3V3 and 1V7 voltage present. Natomist does not have VGH, VOFF, VON, VRREF, GREF.
The DC17DC converter is MAX17126B, which is also powered by IN2 and LX1 pins.
I would like to add that the above arrangement is completely cold or does this system need an enable signal?
Thanks in advance for your help.

Are these values correct and does this mean damage to MAX17126B?
