A few weeks ago th picture quality started to detoriate on the V+ box. It is mostly noticeable on very dark areas of the screen, with a very pronounced pixellation effect.
The bix gas been rebooted a few times and both a HDMI and SCART connections tried; none have resolved the problmes. Sometime it is less pronounced than others, sometimes it is virtually impossible to watch TV at all.
This was further compounded today when the sound started to frequently cut out and in briefly.
I should clarify that the sound cutting out is peristent, it cuts out for very brief moments but often. We lose only one or two words, but that is very frustrating.
The pixellation is owrst on blacks, these often break down into reddy brown pixellated patches. I have also tried another HD television, which also exhibits the same behaviour. That makes it TV and connection method independent, so we are leaning more towards it being a signal issue.
An engineer has called, his diagnosis was singal too strong, so he fitted an attenuator to the cable, upstream of the broadband/TV splitter.
All seems OK, but I have to balance that out by commentimg that the sound had stopped cuttnig out and the picture had improved somewhat of its own accord in the period between my first post and the visit.
Fingers crossed for the attenuator, and many thanks for sorting this out. It is such a shame that we can't get this level of response over the phone from Customer (Dis-)Services.
