No signal on BBC 2/3/4 (Sky +)

Best guess, window cleaner, they never look up when carrying ladders

I think that is the most likely, there are some windows in the courtyard, but other than that it is locked and nothing to go out there for. Who knows, at least it's sorted

Hi,
We have been having the same problems with BBC 2/3/4 and TV4 but with a notable twist, there is a temporal relationship. BBC 2 is fine during essentially day light hours (~07.30-~19.30) and rapidly goes off (first increasing picture and sound breaking up progressing to message 'no signal'). As BBC 3/4 do not start broadcasting until 19.00 we almost always get the 'no signal' straight away. BBC is back to normal the following day but of course we cannot check 3/4.TV4 is bad for 24 hrs. whereas TV4 + 1 is usually fine during the same interval, which would tie in with the suggestion of separating out channels that receive H rather than V-polarized signals. Our service engineer is completely stumped. He changed the LNB and reported a much stronger (65 > 90%) and better quality (~40 > ~80%) signal. This solved the TV4 problem but only when there no splitters in the line. If these were included, there was significant interference. It did not solve the BBC 2/3/4 problem. Shortening the cable from the LNB to the decoder from ~ 30 to ~5m with no splitters on the way gave full reception on all channels but there was still significant interference of both sound and picture quality with BBC 2/3/4. I have noted the comments about dish distortion being a problem and our problems did seem to coincide with the major snow we had this winter. Our dish is an 'environmentally friendly' transparent (plastic) type but I can see no obvious deformity. Are these known to be problematic over time?Any suggestions as to where we and our engineer should go next would be gratefully received.

Hi,
I have a similar question.....

2 SKY HD boxes, and 1 SKY+ box. All three boxes arent receiving BBC1,BBC2 and CH4. Signal quality readings on all boxes are perfect. (They are all on about 75-80%.)

The system is set up with a 60cm solid dish, with a Hirschmann Quattro LNB. The signals are boosted with a launch amplifier (Delta SV435) before going into a Delta 12 way Mutliswitch, and then distributed to all three boxes.
Readings have been checked at the LNB, the launch Amp, The multiswitch and the termination ends of the cable. Every single reading is perfect.

This only just started happening to me last week, and I have had the engineers round who cannot find a problem with any of the set up.

Just wondering if anyone on this forum had any ideas, or similar experiences?
