some channels pixelating recently....

[imish]

Hi all

Past few days some specific channels have been pixelating badly while others are working fine.

Sky 28.2

for the channels that are pixelating (Crime / ID / Star life OK) I have noticed that their SNR is around 65-70% while for BBC HD it is around 95%. i've removed the f connectors and cleaned them before putting them back on - no difference.

just tried CBS - that is around 75% and working fine.

Has been working perfectly for over a year - just having issues for the past week.

any suggestions?

Sounds like the dish has shifted slightly. Any storms / strong winds recently?

[imish]

That would be a shame if the case as the dish is high up and I would need to get an installer to re-adjust.

Could it be anything else?

Could be that the LNB is failing. unfortunately both will require a ladder and someone to check the signal at the dish.

You are not getting your signals from one satellite but a cluster of satellites. If the dish has moved by a small amount you can get perfect signals from one satellite and marginal signals from another.

Update - LNB 2 is OK while as LNB 1 pixelates (certain channels) so that rules our dish alignment. Bought an inline signal amp and that seems to have fixed the pixelating issue.

Further update Guys

LNB 2 = Tuner A
LNB 1 = Tuner B

Tuner A alone - works fine
Tuner B alone - works fine

As soon as I record anything say on Tuner A - the pixelation on Tuner B returns.....Tuner A channel is fine.

I have now replicated this multiple times and its got me a bit :confused:

Any ideas?

Can you try your receiver at a friends house?

i see that you have a dual lnb... so, it could still be an lnb problem as the 2 lnbs are not independent.

good suggestion - will have to get that arranged.

Not sure I follow - I have a 4 LNB Sat Dish with a Miracle Box with a dual Sat Tuner.

Are you suggesting that one port on the LNB on the dish might be faulty?

[abu baniaz]

You can have one port faulty. However, you have tested one at a time. Some LNBs behave awkwardly when there is more than one tuner connected to them. This is why it was suggested to try at another location.

this is what i meant as well.

Check your box is not getting to hot..this will also cause what you are experiencing.

You need to change your lnb, I'm sure of that as I had the same issue. As soon as I changed it no issues whatsoever with the pixelating

how do I do that - the box doesnt seem to have a temp reading anywhere.

on touch it is warm / not hot.
