I had the Full Virgin VIP service installed last week and about 5 mins after the installer left the V+ box stopped responding to the remote.

When i use the V+ remote on the standard stb in my bedroom it works fine. I also have a Harmony remote which i use for all my AV equipment and it won't control it either.
Anybody out there have this problem and if so can it be sorted without an engineer coming out?
Cheers.
