HI, MY samsung PVR has suddenly stopped picking up any signal. I've tried different HDMI cables and different ports on differents tvs but no joy (obviously made sure it was on the right source) It won't allow me to see the Smart Hub so not only can't I watch tv bit I can't watch any on demand or recordimg. The PvR is working in so much as it turns on and I can see the chammels chamging when I use the remote (D001, D002 etc on the display). Any ideas? TiA
