Hi

I have a small problem with my Sky Tv and Freeview Reception.

It seems when I am changing channels on my freeview STB I am losing signal to my Sky STB. The Sky STB picture just seems to freeze or breakup whenever I change the channel on my Freeview STB.

I have been into the Sky menu and cheeked both the signal strength which is normally 68 and signal quality 70.

I had someone watch these figures while I changed the Freeview STB in the other room and they reported that the signal strength went down to 48 and Signal quality went down to 0 for about 5 seconds on the Sky STB each time I changed the channel.

I have both the Sky STB and Freeview STB running off an all ports power pass splitter.

Has anyone experienced this problem or know of a solution to this problem.

Thanks for your help.

Kind Regards
Hamish

Are these results from testing yesterday or in the past? Sky TV changed their transmission polarity on the 31st July, before then you could not watch Sky and Freeview off the same satellite at the same time due to one transmitting using horizontal polarity and the other using vertical polarity. Assuming your cabling is all OK your setup should work from from the 31st July.

Hi

These results are from testing yesterday after Sky changed over.

I dont think I have worded myself properly, when I say the Sky picture freezes or breaks up It does come back on after a few seconds.

Thanks for the help.

Hi All

I am happy now.

I found a new splitter lying around the house and replaced the old one. Sky and Freeview are now working in harmony.

I am 100% certain that the old splitter is faulty as when you shake it it has a few rattles inside it.

Thanks for all your help.

What FreeView STB do you have. Do you have a power pass both port splitter or a single pass. If single pass which STB powers the LNB. If dual pass have you tried turning the FreeView LNB power off and have only the Sky box power the LNB.

Other things to concider, does it happen when you switch between TV1 and TV2 on the FTA box, or does it happen when you change from TV1or2 to TV3or4, reason I ask is that TV1&2 are on the same transponder so the tuner in the FreeView box should not do any thing in that transition, where as it would when changing from TV1/2 to TV3/4.

There are two things that could be an issue, either the LNB power is getting played with on change (it should not be altered under normal operation) or the tuner in the FreeView box is generating some rubbish when it changes, causing a tempory block of the Sky box, in both of these instances it would indicate a fault in the box as this is not normal.

Damn, ive just spent the last 2 hours with the exact same issue. I suspected the splitter was to blame, thanks for the confirmation :)
