I had the same problem.
It does work when you wait to connect HDMI until it has booted, but that is not a solution.
What really helped was flashing the eMMC with the most recent Android (v1511) version.
It seems that even when you boot from SD, it still starts from the eMMC first.
(maybe u-boot was still loaded from eMMC with incompatible settings, judging a bit from:
http://forum.lemaker.org/forum.p ... 515&page=2#pid90541
this should be solved from v1511, but I am only guessing this is the same problem)
So it is not the guitar, not the baseboard, nor the HDMI cable and resetting doesn't help, updating the eMMC Android to v1511 did.
Afterwards I was also able to flash recent Linux versions to the eMMC without HDMI problems.
