The fuse is on the power supplu board, but dont think thats your problem. Is the setompletely dead when you try to power it up? Does the LED light blink? If so how many times does it blin before it pauses for a second.

Hitachi 50FX48B shuts off for no reason !!

If it is shutting off, you can have many things shutting it off. Hitachis are riddled with protect circuits. Excessive current draw from many circuits could cause a shutdown. Best bet is to pull back off and watch green lights on power board, first light off is usually a suspect circuit that would be good to look at (assuming you have one that goes out immedieatley). Some have had flakey regulators also.

Since this is an older non HD set, I would suspect regulator and a large Sandblock current sense resistor mounted right next to it, part / Location #'s elude me at this moment, but they are on the deflection PCB close to where the ac goes into the board from the power cord and fuse/ chokes.

Green flashes then tv turns off

or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.
