Hi there

Today I have been getting the atmospheric conditions have prevented your viewing message on my sky hdi and the red no signal light has been coming up. I tried rebooting several times using the red button but no change.

Funny thing is I connected my hdi decoder using my next door neigbhours cable (at his house) and it worked fine over there. His normal mysky works fine. When I connect it to mine it keeps getting that message and the no signal red light is on. It just started today, has anyone else had a similar problem?? Is it a satellite issue or a normal outage of Sky??

You have replicated the same problem with your neighbours box right?, and your box works on his dish?

Sounds like a dish obstruction/mis alignment, you might want to go outside and have a look to see if there is anything obvious misaligned with your dish,

unless you are competant to realign your dish/LNB you may need to call sky to send out a tech

That sounds like an interesting theory, however, I just checked with my parents they have the same problem. The red no signal light on. I also went to a friends house who had My Sky HDI installed last week, I connected my decoder to his cable and it worked fine.

Could this be an issue with the LNB or something? He had his cable replaced by the tech when he had his mysky installed, however my technician just replaced my box with the new HDi, even though it said on my bill that LNB was replaced. He never went near the satellite.

This requires specialist tranport vehicles and special suits, not all Sky installers have these.


As for the real problem, sounds like the dish, LNB or cabling need checking, outages on any of Sky or FreeViews muxs is very rare, except in cases of genuine rain fade.

I was shooting at it with the .22 the other night, maybe I hit it?

i got this last night for no apparent reason.  Did a red button reset and it went again.  Very odd.

Several HDi users have reported that the signal strength is less than a MySky1 hooked up to the same dish, probably due to the internal switch, so it's entirely feasible that an HD box will drop to rain fade in a marginal signal while a legacy or MySky1 still works. You didn't check signal strength by chance while you were testing?

Two MySky HDi units.

Unit 1: Signal Strength 1 71 dBuv, Signal Strength 2 71 dBuv
Unit 2: Signal Strength 1 52 dBuv, Signal Strength 2 62 dBuv

While unit 1 has a higher signal strength it has had a few lockups and failed to record a couple of times. Unit 2 has not missed a beat; go figure.

All those above signal strenghts are fine, should be no issues with them at all, BER/Quality are more important. I suggest the lockups are not related to signal input conditions in your situation.

Agree as well, I've encountered this error twice tonight and the sig levels were fine but the box was not. I had already had one lock up simply by changing channels. The second lock up within mins of the reboot occured when I tried to rewind from live play.

Finally after a second reboot the unit again locked up this time allowing me to change channels but displaying a blank screen and a few secs later the info about the lack of sig - which I disbelieve.

Interestingly if I just powered the unit on and off using the remote it would not clear the error - a 3rd reboot was required.

Yeah, I was actually referring to DarkKnight's original rain fade problem which was something entirely different to the lockup issue.

Before you get too carried away check the termination on the cable from the dish to the MySky unit - sometimes the crimping gets dodgy.  had that problem recently

Thanks for the replies,

It was actually the F Splitter that the technician hooked up to the satellite which split the signal to our neighbhours (we live in a series of 3 bedroom apartments). What concerned me was that when the Sky tech installed our dish last year I had the signal coming straight to my apartment, seems like when the guys next door got theirs installed sky just split my satellite feed?? Are they allowed to do that?

Anyway I bought a F splitter from Dick Smith and it worked fine, however my signal has gone from 72dBuV/70dBuV(a couple of days ago) to 50dBuV/49dBuV :( looks like the splitter has downgraded the signal but atleast I am getting sky I suppose.

No, they should not put a ground connection betwen 2 seperate electrical systems with a splitter. There are proper ways to do a multi unit dwelling and they should do those, where its powered seperate to the units and they properly ground the dish etc etc.

There is no reason why you cannot split a single feed across multiple appartments, however as richard says ideally the LNB should be seperately powered and the primary splitter should have a CET (communciation earth terminal) which is connected to the mains electrial wiring earth by a 6mm cable.

However if we are talking about a couple of appartments on a common earth system then no real issues, no different than a single dwelling unit feeding a granny flat out the back. I think if it was to be split over more than 2-3 appartments then a proper CET should be installed to prevent the potential of the coax braid going live.

Only other thing to watch out for is that a all port power pass splitter should be used, otherwise if your neighbours turn their box off (at the wall) then you may loose reception, but I think you can assume the installer thought of that and used an all pass splitter. A remote LNB PSU as mentioned will also get around this issue.

50dBuV is fine, getting on the low end but still plenty for the box to work with, the quality/BER figure is the one that you should check has not taken a major dive.
