I am having BIG problems with my ARCAM AV-888

Hi has anyone out their encountered the following problems with an ARCAM AV-888:
The unit gets stuck and the remote will not work on it at all; only until reset via the AC-line will take it out of this "freez".
I can see the menu OSD, but no video is displayed in any input .
Going into any input except the DVD inputs gets the unit into what I call "BLAK MODE";
Is this fixable, does anyone know what's going on????

Did you buy it new? Authorized dealer? Contact them. Arcams service is great. If not, I can give you a list of authorized Arcam service centers in the U.S. Also, is it the 3d version?
