I had the same thing a few weeks ago on my centipede with a G07(bought it without monitor working). F901 blown, couldn't find any cracks on the flyback, but my X01 was OK. Replaced the fuse, monitor fired up for about 1 second, then blew the fuse again. Then i could see a crack in the flyback. So I went ahead and replaced all above listed parts and capped it, works great now.
