If you are getting the message "no signal" this would indicate that there is a problem with the signal from your dish into your box. Even without a card inserted into a SkyDigibox, if there is a signal, you will always get Sky Guide and the free channels.
Try powering off your box, remove the card, check carefully the cables, especially the connection to the dish, reapply the power and then when asked to insert your card you should then be able to see (for example) channel/SNWS">Sky News on 501 and the BBC News channel on 503.
Once you can see any channel, reinsert your card. This should, after about one minute, give you the channels you expect, such as 103, 104 and 105.
If you continue to get "No signal", you dish may have been misaligned, or there may be a fault with the cables and connectors, or a problem with the Digibox. You can see the signal strength by pressing SERVICES, then 4-SYSTEM SETUP and 6-SIGNAL STRENGTH.
Helena Cairns : Should you be referring to a Skybox? and have tried everything mentioned in the heading of this page, then there really isn't left to try, as your problem is either being caused by (1) the dish having moved slightly out of alignment e.g: blown by high winds, (2) failure of the LNB which is mounted on the end of the dish arm, (3) damage to the "external" section of the coax, or finally (4) the actual box having failed, the cause of nearly always associated with its internal power supply.
Therefore, the only way of determining which of the aforementioned applies, is either by trying your box out on someone elses dish system, or alternatively have them try their box on yours, if their box works OK on your dish then your box is defective.
my daugher has just moved in to a rented cottage in Calne, Wiltshire, (post code SN119PG). just got a Samsung TV and reception is sub-standard. She can't get BBC1 channel 1 at all and the BBC 1 & 2, 101 & 102 High-def channels frequently break up. It seems to me from your coverage maps that she should be able to get satisfactory reception, so I think it must be an aerial problem. She says it looks like an old one, probably been up for years. She described it as looking like an 8 element aerial.
Any opinion would be welcome.
I can't get any of my irish channels at the moment, have all the other channels at the moment, I am afraid to switch my tv off at the mains in case I LOSE all the channels, this has happened before. Can you help please
Many parts of Calne are served by a local transmitter close to John Bentley School. It does not provide all the services, it being a 'Freeview Lite' transmitter. Look at http://www.ukfree.tv/transmitters/tv/CALNE to see a coverage map and the available TV/radio services from this source.
If, however, your daughter lives outside the coverage area, she may be able to get signals directly from the Mendip main transmitter - all depends on where she lives.
You mention an 8 element aerial. If the rods are vertical it is most likely pointing towards the Calne transmitter. The fact that it may have been there a few years is not a reason to change it unless it is proven to have become faulty - a fairly rare occurrence.
I used to live near Calne so know it quite well and a Post Code would help to identify her location to see if she might get Mendip or have to stay with Calne and not get HD or commercial programmes as yet.
