@rohansolo "Voltages on power board are correct when plugged in." we need to know where you measured for those and what voltages you got. Then we need to see your boards. Remove the back cover and post a couple of good, well focused and large size images of those boards, with your Question. [guide|21499]
Let us know what voltage you measure on the backlight connector and what happens when you dc the backlights? Does your TV stay on/turn on?
This can have a lot of causes. From a bad main board, to a bad panel etc. and yes, the backlight strips as well.

@rohansolo test the voltages on your T-con board. Let us know what you get.

The boxes on the right hand side are for the gamma chip. Start with the highest point and work your way down (GM18-GM1)

Also check the 6R8 coils and see if you get power on those. Black to ground and REd to one of the legs.
