hels: You havn't included a postcode, so we dont know where you are in relation to the . The transmitter looks OK, and in most cases, its peoples systems, not the transmitter thats the problem.

Could be a couple of things: The most likely is that you've got a loose connection or other problem with your system. Since your problem started when you changed the TV, change the aerial lead, since its possible its come loose, etc. Could be the TV is tuned to the wrong transmitter - check that its the right one.
