Bev Pearce: Check the information for the transmitter - if it says its fine, its probably your system. Start with the simplest problem - is the aerial lead connected properly to the back of the TV?

Struggling to get any HD channels on this transmitter, all other frequencies tune in 100% signal strength/quality. Is there an issue?
