Samsung bn95-00944b t-con

[mmpi]

Hi all, I have a Samsung tv that has a vertical side of the screen very dark. The backlighting is good. Doing some testing on the t-con board bn95-00944b and am not sure about the voltages i should have on the inductors. Does anyone have a list of voltages? There is one inductor that has 0v on it, while its mosfet has 15v in the gate driven by THV3056 out_vgl pin. Am guessing the thv3056 is defective. Thanks

Attached a photo of the t-con board that has problems. These are the current voltages on inductors:
1: 2.5v
2: 1v
3: 0v
4: 15.3v
5: 3.2v
6: 12.3v
Also the voltage on the main fuse of t-con board is 12.35v

On T-Cons, it happens that one inductor sits on GND, then it forms a negative voltage to power the panel (VOFF = VGL = VGOFF = VEEG = from -5V to -9V).

Hi all, attached a picture of the screen with fault.

I have a simular issue after I swapped ribbon connectors and the TV didn't start again, so now I have leds on low voltage and no picture. The CPU is also running hot since this experiment!
