Windows 7 Media Center failure

[ZigZak]

14 days ago my Media Center worked perfect, but today I've lost the picture in my Media Center.
It finds the channels and the sound are OK - but no picture.

Any ideas???

As supplement to my post above I can tell, that the text-pages of my channels are working OK,
and previously recorded tv can be played with sound and pictures.
