If it's the fuse, they can be replaced. They are soldered onto the power supply board and not accessible from outside the case. A technician could check this by removing the back cover. If that is the problem, I estimate the total time at 20 minutes for repair. The fact that you don't see any power light strongly suggests that it may be the fuse.
Older tvs used to have a fuse holder that the user could access to visually check the fuse but this brand does not have them from my experience. They did this to cut the cost which is unfortunate.
