Has anyone discovered a fix for this yet? My TV keeps losing all non-HD channels and simply displays the test card style screen stating there's no signal. This can happen whilst flicking through channels (eg. one minute BBC one standard definition is there then you flick a few channels and sudenly there's no signal and it's gone). When this happens if you switch to channel 101 (BBC1 HD) it displays fine, no issues whatsoever yet all the non-HD channels (channels 1-100) are blank?? If I then autotune the set they all magically re-appear. I know there's not an issue with the aerial becuase my other TV never has this problem. It's getting more and more frequent and it's driving me mad!
