In the last couple of weeks my picture on certain channels started pixelating badly. Mainly HD channels. BBC1 especially and even loosing signal completely. Is this a service problem? I have already rebooted the TV box once but problem still persists.
If nothing's listed there, and especially if you've had the problem for some length of time, there's a fair chance the problem is local to you and Virgin don't know about the fault.
The forum staff will probably pick this thread up in a few days/week and help out, but this is primarily a customer-forum so I'd suggest you call CS on 150 from a Virgin landline, or 0345 4541111 (landline rates) from any other phone and report your fault. The chances are it'll need a tech visit to fix, so the sooner you report it, the sooner it should be resolved 😉
