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"; NO PICTUR NO CONTROLL . Is this fixable, does anyone know what's going on????
