      No Sat Signal everyday at 10am-2pm

      Hi, i have recently moved into a new flat which shares one dish and booster between me and 3 other flats. I have a Thomson HD box but with only one feed into the flat so i use single feed mode. I dont have the HD pack, just normal sky+ with added music channels. I have however tried my other Amstrad and Thomson sky+ boxes to see if my problem still exists, and it does.

      My problem is that every single day nearly bang on 10am the picture on all satellite channels will start to break up and then go to "No satellite signal is being received". BBC, ITV and channel 4 channels are uneffected, along with Comedy central+1 and a couple of music channels and DMAX. However, at around 2pm the channels that were effected start to break up and come back on again to normal signal strength through to the following day at around 10am. Im usually at work but have had several failed recordings when im out, and have been on holiday last week so have pin pointed the times almost exactly.

      I have pretty much made sure every other electrical item in the house is off previous to 10am in case something was clicking on at 10am like the boiler etc but its still happening. I have tried unplugging the box, resetting it, switching the LNB off and on etc but sometimes this makes the other channels lose signal also.

      I live in a flat over a shop which repairs washing machines and hoovers, and at the rear of the building there is a mechanics/work shop, these two places are open to business from 9am till 6pm, i thought perhaps something in these places was perhaps knocking out my signal, but why only between 10am and 2pm, surely whatever they were using would be used to varied times. This is also a problem on a sunday however, and neither the shop or garage are open.

      Please please, can anyone think of anything i can try. Thanks

      Do any of the other Flats suffer the same problem?

      No, only mine, only 3 of the 4 flats actually use the sky, the other one uses the other ariel for freeview.

      Would it be possible for you to switch the LNB lead (at the LNB end) so you use the outlet currently used by the 4th flat who doesn't have satellite? It might be you're connected to a faulty outlet from the LNB. This sort of behaviour does occur in Spain where people have massive 2 metre dishes and very sensitive LNB's - it's due to the earths atmosphere warming up and cooling down during day/night. However you obviously don't have this sort of problem!

      The booster is located in the loft which is locked by the landlord im afraid. I really need to speak to him about this i guess, was just wondering if there was a fix i could do before i call him as hes not the best of landlords. As you say, living in Scotland i certainly dont suffer from heat problems lol Even if the connection was faulty though, would it be time specific like it is?

      Here's a similar problem:

      Sky TV works fine during day, evening = dead

      The times are different but the principles remain the same. There's not much more you can do yourself as any fix for this problem is going to involve getting access to the loft. As your problem appears to be fairly time-specific, it's got to be external interference of some sort. An LNB change, cable upgrade to good double-screen standard, connecting to a different port on the LNB or loft box, and even moving the loft box itself may help.

      Don't rule out external transmitters. Lunchtime is when takeaways etc fire up their comms ( whatever they may be ). Is your dish etc facing onto the main street? Any new businesses opened up recently? An unlicensed transmitter somewhere may be causing the problem. Ofcom do an Interference Investigation Service but that costs money ( 50 ) and your landlord almost certainly won't be interested as the problem is confined to lunchtime. Sky also have specialist teams with spectrum analysers to identify frequency problems, again, these cost.

      At the end of the day, a no-cost solution may be possible by getting into the loft and doing as has been suggested above, but you may ultimately be stuck with this.

      Thanks for that last reply, i am indeed close to a main street, i live on the street behind, and the dish points towards the main street, there are several takeaway's, along with the garage and other small business's that could be the problem. Its not a great problem as i am at work nearly every day, but its frustrating at the weekend or if i want to record something. I also dont work on a monday and find it quite annoying that this happens. I was recently off for a week and thats when i managed to sort out what times it was happening at.

      Re: No Sat Signal everyday at 10am-2pm

      Well today seems to be a little different. No signal from when i checked this morning at 9am, perhaps previous to this? However, i left it on channel 5 and the signal regained its self around 10:30am and continued to just before 1pm when it started to go blocky and eventually loose signal again. It has been left on channel 5 since then, it is now 3:15pm and still no signal. Btw it is a No signal number 28. It has a Nework ID of 0002 and the Transport stream is 07f9 but when i have no signal there is no Signal quality or strength and the Lock indicator is switched to NOT LOCKED.

      I have also encountered a small problem with recording from the single feed. Not sure if this is a morning problem yet or not, i have tried recording several different programmes in the morning around 4am-6am. It seems that if they are on the same channel one programme after the other, the second programme wont record and will say failed, no signal. Is this due to the single feed? I have set the Add to start and end of recordings to all the different settings but to no avail. It seems that it wont record the following programme if one is recorded previous to it on the same channel. Any ideas?

      Sky Digibox Faulty - poor reception? Error 28 "no signal". This usually indicates a momentary or intermittent loss of signal. This could be a true loss of signal or a fault in the Digibox. Rebooting the Digibox may fix it for a wile but you should investigate to determine the cause.

      Another post says "28.... NSS is being recieved" and this was when only some of my channels were affected and if you left it on an affected channel for a few minutes it would come on. But if you dared change the channel to another affected channels... you would have the same wait.

      We ended up changing the box and problem resolved."

      Yet another said "The digibox overheats during the warmer parts of the day and we needed to make sure it was very well ventillated."

      I think your problem with recording consecutive programmes is a known problem in single feed mode. You could try setting the recordings MANUALLY so you record the programmes as a single operation.

      Skywatcher77, please confirm that your Anytime is switched OFF ( it must be disabled - the Default setting - in Single Feed Mode, otherwise these sort of signal problems occur ).

      As you have a Thomson HD digibox ( how old? Does it have good ventilation all round?), you could open up the box and have a look for signs of leaking/bulging capacitors on the PSU. These cause no end of performance problems. Failing capacitors often leak/bulge at the top ( see pics in link )

      See:

      A screwdriver is all you'll need for this inspection. It's easy peasy, just take your time, and be careful with the the plastic PCB.
