@LostZimbo,
Have you tried removing the emmc AND throwing the switch which tells the system not to use the EMMC AND pressing the reset button, then doing a clean install of a distribution on an SD card which you are sure is good?
As @as400 has indicated, it really helps to be able to see the u-boot messages by using the serial cable, but by trying to boot only from the sd card and by being sure the emmc is not involved in any way, you should have some additional information.
How have you been writing the image to the sd or emmc--dd, etcher, something else? Had you made any changes to software or hardware immediately before it stopped booting? Let us know what happens.
