Sony KP-46S17, turns on then shuts off

I Have a Sony KP-46S17 rear projection TV that turns on then shuts off within a second or two.  When it shuts off, it just sits there with the power light flashing.  I blew it out and vacumed it out and found a glass fuse blown on the D-Board.  (125V - 3.15A)  I replaced it and nothing changed.  Any ideas what it could be?
