Hi Stephan I once had a Cube with a similar problem and finally realized after investigating everything - inboard cardsand softwares - that the multipins connector was at fault. Normal wear apparently?? I hope this is not your situation because even though I tried to get the proper replacement part -local, national, continental and even europe search- , I got nowhere - after alll our Cube units, as good as they are, are now labelled as a vintage unit???- so finally I had to buy myself another Cube, believe it or not. Now the good side: a few months later, a friend of mine who is a certified electronician dealing with hardware fixes and cures has been able to restaure the old unit connection and it finally worked - with a special home-made connector -, so my daughter today uses this unit... with a VGA CRT screen wth no more problem. The extra piece added wwas unstable when using the beautiful Apple CLD screen which is collecting dust in my basement...what a pity! After everything failed, sometimes the obvious remains to be looked after...
