This is interesting, I am a new Iyonix user with a very new Iyonix. On 
trying the original error on my machine restart gave a screen of black 
& white horizontal stripes which RESET did not clear. Switching off at 
the back and leaving a bit restored normal service.

I don't know if this helps or confuses the issue!
