Few days ago I had a virgin engineer to look at our second box in the bedroom, a V+ box, which was stuck on LD01. He arrived, took a look, replaced the box, booted it up and it worked and left, I thought this was the end of it! Since then the new box is getting stuck on LD40!! I have worked out it is an issue with the White cable. I've tried to tighten it, wiggle it, and have unplugged and replugged the box in a couple of times, sometimes it works for a bit then turns off and shows LD40 again! Do I need an engineer again or is it something we are doing wrong??
