Hi people, I hope someone can help.  My Avant doesnt start sometimes. If I switch off at the mains and then on the Green Standby bar comes on and I can then switch on, and the TV works ok re video and audio. The software is so slow.  It takes a while to speed up.  e.g. to change channels it takes about 3 attempts for all 3 numbers to appear and then the change of channel happens.  Has anyone else experienced this or has suggestions to fix it?  My nearest B&O store is now, after closures is 150 miles away.  Many thanks Glyn
