Place a jumper between these points, disconnect the LVDS cable and check again that the voltage appears on VGH.

Using technics described into this videos i've been able to restart my TV:

Today i still face to some lines and bad colors, I need to reduce VGH voltages and rebuild some CK lines, but i'm moving forward.
I'll keep you up to date, i'll put a DC to DC to reduce the VGH voltages of the whole panel, just need to buy and receive these parts

I've cutted the VGH line on the defective driver panel side and took the 14v from the caps just near and make the connection.
I've bought a DC to DC but the wrong one, step down don't work for me 'cause I guess the current consumption switch the main board DC dc into safe mode.
I'll buy a step up DC dc to take the incoming 12v and convert to 19V to preserve the panel.

I've followed mostly the yt link posted in post#91.
Just used other videos on the same chanel to have more confidence on action to perform.
On one of his video he explained shortly how to tale the 14V on a cap close to the VGH line.
I'll need to improve some solder and place the DC to DC Step down, so i'll be able to take some pictures to show you.
Is there something that you would like to get in details?
