Steve Mak: Waltham (H polarisation @ 19miles / 49 degrees) is indicated as providing the best signal and with the terrain indicator showing a clear line-of-sight between the transmitter and your location, this of course excluding any man made structures or vegetation such as trees.

Ian: The easiest way (albeit not 100% accurate) to determine if a problem is caused by 4G is to try a test by "manually" tuning in the highest mux channel used by a station and making a note of the signal level received, in your case this indeed being BBC1, then proceed to do likewise with the second highest and so on, if on completion the signal strength of the muxes is seen to reduce as the channels numbers go up then 4G should be suspected.
This form of test only being applicable to stations where all muxes used by same are rated with the same output.

Rhonda Evitt: As white Sky+ boxes are amongst the older devices around then although the problem could be caused by a fault having developed in the boxes internal power supply, it could however also be due to the dish having been blown slightly out of alignment.
But though, try swapping the two LNB inputs over followed by disconnecting the box from the mains for 30 secs or so before powering it up again, if this action restores a picture then the coax feed that was "previously" used by the LNB1 input is defective, possibly by water having entered the "F" connector on the dish, if though it doesn't resolve the problem then the dish could be out of alignment.

Sean Cassidy: Well, that could suggest that the main feed from the aerial is connected into the lounge socket and is then being fed from that point into the bedroom, but though with a signal loss in the process, therefore you should unscrew the lounge socket and have a check at the wiring behind it, if it looks OK then unscrew the bedroom socket likewise checking it.
You should also carry out a signal level check on the box connected into the lounge socket, not only checking the strength but also if the quality of the signal is seen to fluctuate to any great degree, because your problem could also be due to the signal level received from wherever being a bit on the weak side whereby the extension into the bedroom is further reducing it to a critical level.
A post code would have been of assistance as this would enable details of the transmitter covering your area to be checked out.

Rhonda: If the problem remained the same after having tried the LNB input swap then that points to either the dish having been moved slightly out of alignment or the box itself being faulty, which of the two applying being easily pinpointed if you managed to try your box out on someone else's dish, or alternatively theirs on yours, even if on an standard installation that only uses a single down lead as you only require a connection into LNB1 for viewing, LNB2 mostly used for recording purposes.

Sean Cassidy: Now that your location is known then yes! the signal from Bilsdale at just under 16 miles / 149 degrees is indeed indicated as having a clear line-of-sight to your location.
However, although you have previously checked the points mentioned did you find that the lounge socket had more than one coax connected into it? the reason I ask being that the bedroom has to be fed from somewhere, and its this somewhere thats likely to be the source of your problem.

Sean Cassidy: In addition to that previously said, another possible reason for your problem could be due to interference being picked up in the coax feeding the bedroom socket, or alternatively that the cable run to the bedroom is not continuous and is joined in a less than satisfactory fashion at some point along the route, but problems of this nature really require investigation with the aid of a ohms meter on a low setting as its the only satisfactory way of verifying the continuity of a cable.
You should though still carry out the aforementioned signal test on both sockets for signal strength / quality comparison purposes between the two outlets, because if interference is being picked up in the bedroom feed then although the strength may remain virtually the same the quality will suffer from fluctuation, however if the strength and quality vaults up and down then that can indicate a bad joint.

Bruce: What brand / model number of TV or box are you using? as whatever you are using has to be fitted with a DVB-T2 tuner and not DVB-T.

john powell: The main station Sudbury @ 15 miles / 249 degrees H polarisation is indicated as being able to provide good reception, although to be perfectly honest about it same room aerials are never really satisfactory unless the transmitter is within sight, although even then you can still experience problems caused by movement within the room.
That said, same room aerials can however perform better than expected if mounted in the loft using a coax extension lead.

Toni B: Should you be referring to your Philips 42PFL7606H/12 then this model is unable to receive HD signals as its only fitted with a DVB-T tuner, HD reception requiring DVB-T2.
However, if you are referring to another model, or alternatively a Freeview HD box connected into your Philips via an HDMI lead, then Bacup's HD service transmits on mux C40, Haslingden C29 and with Winter Hill being on C54, and so if the EPG numbers mentioned by Michael are missing from the programme guide then try a manual tune on the HD mux channel number appropriate to your area, which on checking your previous postings would suggest that you are located extremely close to the Bacup 50 watts relay and which if using a roof mounted aerial could possibly cause problems with HD reception due to an excessively high signal level swamping the tuner, this obviously not applying to the bare Philips DVB-T model referred to.
