There seems to be more going on with the set. If the backlight assembly or inverters failed, you should still be able to see a very, very dim image onscreen, because the video processing is still functioning. But seeing nothing at all, means either multiple failures (video proc, backlight, inverter(s), or some combination of the three which is really unlikely. It seems as though there's a power supply problem, since more than one condition is present. You may be able to get a supply from shopjimmy.com, if you're technically inclined and comfortable enough to swap it. Again, not sure of price, but it may be worth a shot.
