MINIX NEO X8-H doesen't start up

Hello All,

I have the Minix Neo X8-H for some weeks now. The neo X8-H have worked perfectly without any problems.

Since yesterday when i try to start up the Neo X8-H i see the Minix start up screen in purple for just 2 seconds. After 2 seconds the screen went black and stay black. The Neo X8-H does not start up.

I have tried several new hdmi cables and tv's without any result.

Have anyone got an idea or suggestion what can be the problem? Thank you in advance!

Michaell
