Gerda : If you are losing sound from all of the TVs connected into the Sky boxes RF2 then try using RF1 as all you will lose is the ability to change channels from the bedroom TV's, that is should you actually be using a magic eye facility?

However if using the RF1 output makes no difference then connect one of your bedroom TV's directly into the Sky boxes RF1 output socket and check if the sound still drops out, because if it does then that can indicate a fault on your Sky boxes RF modulator and so try resetting the box by placing it into standby for about a minute or so before switching it completely off, then after about 30 seconds powering it up again and allowing it to search for listings, giving an update on results.

I had sky HD around the house using Distribution amplifier in the loft. This had to be changed and now although we get great freeview signal we have no sky in any rooms apart from direct from the sky box. We are using RF2 and have changed it to on on the box. We now get fuzzy picture for sky on most tv's. Have tried magic eye and a bypass, but the new distribution amplifier says it has a bypass built in. What are we doing wrong. Someone mentioned in the many shops we have asked for help that the silver box thing would work. Tried this and it didn't. They also suggested changing the sky frequency I think, as we have a strong digital signal, but I don't know how to do this and do not want to lose sky altogether... Any help would be brilliant please.

Wendy: If the distribution amplifier is the only thing that was changed then this should not have affected the Sky boxes RF2 feed to the other rooms, you should temporarily try removing the magic eye from the equation and change the boxes RF output feed from RF2 over to RF1, checking the results of this action on one of your bedroom TV's

As far as changing the RF output channel is concerned, this can in some cases result in an improvement to a grainy picture, although it has to be said that some newer boxes are known to suffer from a poor quality analogue output, however you can change the channel that its presently set on from the same menu as you used to switch the RF power on, because if the RF channel that's presently used is under 62 then change it to 68, saving the new selection.

Once you have completed this task select the "analogue" tuning menu on one of your bedroom TV's followed by carrying out a retune on same, this being for the purpose of recapturing the analogue signal from the Sky boxes RF1 / 2, not forgetting to store the channel once you have found it or it will vanish again when you change the TV back to Freeview.

If easily accessible, maybe you could inform me as to the model number of your new distribution amplifier, likewise the number on the old one if you still have it.

jb38: some new amps are 4g protected so they won't let channel 60 through to 69 so if the sky box is on any of these channels they won't get a picture I have seen it.

Mazbar: Many thanks for the info, this aspect being something which I do have to admit had slipped my mind since having seen it mentioned a short time ago in a Philex catalogue.

Wendy: On the basis of Mazbar's info, should you subsequently find that your Sky boxes RF modulator is already set on a channel in the 60's then try it on something much lower, because if this resolves your problem then this strongly suggests that your new distribution amplifier is one of those latest types Mazbar referred to.

However, if by any chance this doesnt completely resolve the problem then this might simply be caused by you having accidentally chosen a channel used by your local Freeview station, and so try another channel.

I am unfortunately unable to advise on the channels to "avoid" by being unaware of your location, this being why its always advisable to include a post code (or one from nearby) with any queries involving reception.

The box we have is it SLx Gold 8 way amplifier with Digital Bypass - R13W25. We had a SLX8 it didn't have a number on it but the UHF was 470 - 862 higher than the new one that is 470-790.

Wendy: Thanks for the update, but with regards to the number provided of R13W25 this does not appear to be listed in the SLX / Philex catalogue, although one is seen that does match up with what you have said, it being a 28105RG model.

However irrespective of that, the fact of its top frequency being limited to 790mhz means that its operating range is limited to Ch60 max therefore the signal from the Sky boxes modulator will have to be set under this.

Your P/Code indicates that you are covered by the West Runton PSB only relay (no commercial channels) and your full service transmitter is Tacolneston, albeit that the reception predictor suggests that you are not in a particularly good area for reception from the latter, but as far as the Sky boxes RF modulator is concerned I would restrict your modulators channels to any between 31 - 37 to avoid the possibility of clashing with a Freeview channel.
