I hope I'm not going to sound too much like a novice
I've had Sky installed for a few months now (since July) and for the past couple of weeks, a few channels haven't been working properly. It only happens for CI, Documentary, Fox News and Fashion TV when, at about 9pm, those channels go dead (black screen) and I get a rain fade screen error after about 5-10 seconds. Then they resume at around 10am the next morning. If I don't get the black screen straight away, the channels pixelates for a while, then get the rain fade thing. The weird thing is that all the other channels work fine, which is really confusing and everything was fine and dandy until a couple of weeks ago. It wasn't as bad at first though, because the channels would start pixelating for a few minutes, then the screen would go black and then th picture would resume after a few minutes.
Now here's the hard part...I called Sky (and got a few really vague answers like "those channels stream all together so if one has a problem the others will be affected"), and failing the usual troubleshooting over the phone, they sent techs to my place twice. The first time the STB was replaced but that didn't fix anything. The second guy said it might be due to a weak signal because the cabling was fine and so was everything else. What he noticed was that the "Quality" little scroll bar on the Signal Set Up page keeps fluctuating then decreases bit by bit. Today, on CI, the quality scroll bar was on 100 all day, and started to go down at around 8pm. After that the screen went black just before 9.
Of course, the couple of times when the techs came the channels were fine, then stopped working after 9ish The second tech said the quality of the signal might be due to the fact I live in an apartment building with one dish that services the whole complex (a multi dwelling facility) but then again, we had no problems until recently, so I'm not sure. I don't really care about Fox News or Fashion TV but I do watch quite a bit of CI and Documentary channel so it's becoming a bit of a problem.
If anyone had a bit of advice on what might be causing the problem I'd really appreciate it Failing that I may need to speak to my building manager and have someone from Sky Commercial come check things out (this was the second tech's advice).
