Samsung LE40A456C2D, no picture

[amennone]

Main -Board BN41-00980B
Power BN44-00197B
T-con T400XW01 V5
Defect: Lighting o.k., audio o.k. no image, scart output image ok.

The F01 fuse is blown, the cause is due to U101 = tps65161 broken. After replacing the U101, I have the following voltage values on the T-CON:
AVDD = 15V
VGL = -6V1
VGMA1 = 15V
VGH = 27V pin 1 of U103 = RT8901
VGHC = 0V
V1D8 = 1v8
V3D3 = 3v3
The VGHC is not present (output from pin 2 of U103 = RT8901). With the replacement of the U103, still no voltage
VGHC.
I gave 24v on the VGHC point, colored vertical lines on the screen, no image.

Voltage measurements U103 = RT8901

pin
1 = 27V        8 = 0V
2 = 0V          7 = GND
3 = 0V          6 = 4v9
4 = 3v3        5 = 1V

I enclose the diagram of the T-con, even if it partially corresponds to that of the T-con in question.
Thanks and good job.
