Daniel: You haven't bothered with a postcode, so we can't find out if there is a problem with your transmitter, but its unlikely that a transmitter would lose 90% of its output for 5 days at not get noticed.
Logically, its your 'aerail', or at least something connecting your TV to it.

Daniel: A postcode would have been helpful (you can just put into the website when asking a question, etc), but since you can see that Sandy Heath has no problems, once again, you are advised to examine your own system.
