Default JVC TV Model LT-65N675- No picture

Hi guys,
This set has no image. The back lights are running but the TCON seems dead.
The fuse on board is ok, 12V is present. The problem seems as if there are voltages missing but due to weird markings I cannot see VGH clearly. Anyway, I disconnected both ribbons feeding the panel to see if my voltages come up but they don't. Up to know I was looking to purchase a complete used tcon board but they are not available.
Can anyone who knows these sets guide me so that i can diagnose the fault. I believe it to be the DC to DC buck converter.
I have a image not to good quality but now that I know that i need to repair it i will remove it and zoom into its design.
I think JVC might be similar to your RCA products

Any help would be greatly appreciated.
