Did you get the name of a good supplier? I have a Kryptview A850 and have had a line off a nice chap for some years now but he appears to have disappeared and anything I watch just stop, starts. I don't know whether it is the line or the box and not sure where to start. I have messaged him but no reply which is not usual so wonder if I need to get a new box which and if a new supplier who. If you have any recommendations I would be grateful. I am scared of posting too openly too.
