Over the past week or so I am getting pixelation and breakup on all channels, particularly when I'm trying to watch the rugby!
On this thread

https://www.geekzone.co.nz/forums.asp?forumid=106&topicid=214860

normal figures are quoted in the 75-82 dBuV range and quality 12-13.

According to the system diagnostics I on the Mysky the signal strengths are all down at 64-65 dBuV (except tuner 4 at 73) and quality between 11.9 - 13.6.
I can get all channels, the picture breaks up but doesn't get to the rain fade warning (fine weather outside). Is this indicative of a problem with the lnb or maybe dish alignment? We have introduced no new electronic devices in the house to cause any interference. The current lnb is probably about 8 years old. Problem seems to be worse at night.
The breakup affects both sky decoders in the house. Just want to discount any obvious things before calling a Sky Technician out.

ours recently started doing much the same.

 

 

 

family ended up staying home and organizing Friday morning resolution for a sky tech out - they couldn't bear missing the rugby -.-

 

Interesting to hear it also affected you over about the same time period.

 

 

 

I wonder if sky changed which transmitters they were using?

8 years... probably a older dual LNB failing in the cold. 

 

could be power related

 

could just be a failed LNB, if sig is that low more likely lnb or lnb drift.

Thanks. While I had the signal strength display up, tuner 1 momentarily jumped to >82 then straight back down to 64.

Out of interest, what signal strength would be considered acceptable?

On calling Sky to get a technician out, the CSO got me to do the normal things, resets, disconnect/reconnect the dish, etc but also asked me to change the lnb setting to 10.745 (originally 10.750). I now have to wait until later tonight and see if the same problem re- occurs. I guess this is the lnb drift referred to above by wingbat45? When I quizzed the CSO it was evident that she was just reading off the to-do list for this particular fault, but I guess it's better than paying for a technicians visit, so it may take a bit before I actually get some onsite if necessary.

If it is a LNB failure then isn't it free of charge to fix?

The shift to 10.745 has apparently resolved the interference problem (for now). But by my research, it is indicative of a failing lnb. So I intend to contact Sky and ask them to replace the lnb at their convenience. If not, then when it fails they will need to credit me the portion of my monthly subscription prorated for the time their equipment is unusable because they know it is failing.

Book a tech to come out if sky have not done it already, the drift will only get worse and you will need to change it to 10740 to buy you more time.

 

They will not credit you for loss of time USUALLY since you have called, but get them to sent a tech out, he should put his meter on the end and see lab drift.

 

LNB is skys fault not yours and the tech will check the alignment at the same time.
