bounty hunter Posted March 8, 2012 Share Posted March 8, 2012 Currently in southern Greece and experiencing problems as follows ~ System ~ Oyster vision 2 with 85cm dish fitted on van when bought second hand last year. Symptoms ~ Driving down through Germany it was taking 2-3 attempts to find Astra 2, system telling me "satellite not found". Just presumed something in way and never bothered as we always eventually got it. On entering Italy nothing so switched to Astra 1 and still nothing. Not really bothered about tv so just carried on to Greece tried again and still nothing but dish keeps searching and does not display ."satellite not found". Actions so far ~ As I knew nothing about satellite out came the instructions which advise changing "skew angle to -12 degrees". At this popint didn't even know what LNB was but it's amazing how quick you learn. On to roof and LNB is currently set at -20 degrees. Have tried various positions for LNB but still nothing. Have tried re-setting system using control panel and no difference. All other functions appear to be working and satellite does respond to requests from control panel. Question ~ Can LNB go wrong As we are on site 150klms from Athens it's not too bad as we have a free remote connection so we do have Astra 1 but we are moving on Monday heading to Turkey and would like, if possible, to have system working as Formula 1 starts on 18th.. We have internet today and don't think we will have it again till 24th so can only respond today. Many thanks in advance. John Link to comment Share on other sites More sharing options...
colin Posted March 8, 2012 Share Posted March 8, 2012 Yes LNB's can go wrong, I had to replace two out of the five on my home system last year. Another (possibly more common) problem on movable dishs is the cable joints coming loose or damage to cable, check them first. Note that reception of Astra two in Turkey IMO will not be possible with your dish size, but F1 is availible on Astra 1 station RTL, Not sure if you'll be able to pick that up I guess so, also will be in german Link to comment Share on other sites More sharing options...
bounty hunter Posted March 8, 2012 Author Share Posted March 8, 2012 Thanks Colin. Can I fit any LNB or does it need to be an Oyster one? The one fitted is made in Czech Republic. Walking round site i have seen 1 or 2 redundant dishes and wondered about fitting one of these. As a matter of interest how does a satelllite work as there is only the co-ax cable going to LNB?

colin Posted March 8, 2012 Share Posted March 8, 2012 I'm afraid I don't know enough about Oyster to advise you on LNB, note there might be a common fault with Oyster that someone might know about. The spec for LNB's has been same for well over 10 years now. The 'co-ax' for Sat is of a higher spec than normal tv, it has to pass differant freq signals and also send back 'signal' to switch LNB.

johnnerontheroad Posted March 8, 2012 Share Posted March 8, 2012 I have the same problem with my Qyster (2006) emailed Oyster but no reply yet. Have tried some of the fixes given on here and other forums but no luck. so will watch this tread with interest. Dave Link to comment Share on other sites More sharing options...

Keithl Posted March 8, 2012 Share Posted March 8, 2012 Have any of you seen the 'Satellite for Caravans' website? If not here is a Link. HTH, Keith. Link to comment Share on other sites More sharing options...
w1ntersun Posted March 8, 2012 Share Posted March 8, 2012 What type of receiver do you have. A lot of people are having trouble with sky digiboxes since the astra 1n was launched and the astra 2d was decommisioned on the 23 FEB. People with freesat boxes are getting even better reception now Richard at Conil Spain Link to comment Share on other sites More sharing options...
Mike B. Posted March 8, 2012 Share Posted March 8, 2012 Hi Before you fit a new LNB if you are using a Sky box try this transponder reset. I had same problem late last year when Sky changed the transponder without telling anyone! Switch Oyster on allow to go to automatic search, Hold right hand > button in , Do not let go Frequency numbers will come in led screen Change to 11307H or 11178V with left < button When complete release buttons and allow Oyster to lock on (normally about a minute.) Hope this helps Mike Link to comment Share on other sites More sharing options...

Colin, why would you have 5 LNBs at home as this requires 5 dishes! We have one dish with a quad LNB which means that the LNB can receive one signal from the air and split it into 4 so that we can run two twin-tuner Sky+ HD boxes. Just curious as you can even have an 'octo' (8 signal) LNB these days. Link to comment Share on other sites More sharing options...

The Astra 2 dish has a quad feeding two IDTV's and one PVR. The other two dish's each have three LNB's two of which are offset. One of these days I'll get around to installing a motorised dish.
