@zmafazel if your power LED does not come on , that means the power board doesn't get power. Check the cable going into your TV. Make sure you have power on that. After that, you need to remove the back cover from your TV and check the fuses on the power board.

Not sure where in the World you are located in, but this is not (yet) a common model (I checked the KD-75X8500G since your number seem to be flipped). Anyhow, post some good pictures of your boards with your QUESTION so that we can see what you see and hopefully provide more guidance.

I show a slightly different board for the KD-75X8500G but of course the same idea. Check the fuse and replace with whatever is required and written on the board.

Hi @zmafazel

Do you mean the fuse in the TV or the fuse for the wall socket power?

If you didn't check the fuse in the TV here's an image of the KD-75x8500G power board that shows where it is located. (I assume that this is the model number that you meant to type)

Disconnect the power from the TV and then remove the back cover and use an Ohmmeter to test the fuse. It should test short circuit i.e. 0.00 Ohms. If it tests OL or infinite Ohms it is faulty and needs to be replaced.

Search online for a T6.3A 250V ceramic axial fuse to find suppliers that suit you best. The T in the fuse rating is important as this indicates that it is a slow blow fuse. A standard fast acting fuse having the same rating i.e. 6.3A 250V would blow immediately the power was connected due to the high inrush currents that occur when the power is first connected. This current is only there for <5mS but it will blow a fuse whereas a slow blow fuse will hold until it has subsided. The ceramic specification means that if it blows it won't shatter and spread all over the place as can happen with ordinary glass fuses. The axial means that it has leads so that it can be soldered onto the board
