Using a serial debug cable will give you a better idea of what's going on. It will not always let you know exactly what the problem is, but based on what you get as output, someone here could give you a better idea what's happening.
Passed that . . . try flashing this to sdcard, and booting from it. http://debian.beagleboard.org/images/bone-debian-7.5-2014-05-14-2gb.img.xz This is an older image, and I have a good reason as to why you should attempt booting from this. Older eMMC images can interfere with newer sdcard images at boot. This should give you( us ) a better idea what is going on. Typically though, with an older 1st, and 2nd stage boot loader, if you press and hold the boot button at boot. the board should be forced to boot from, and use the 1st, and 2nd stage bootloader from the sd card, instead of attempting to use the boot loaders from the eMC . . .
