Can I get this clear. You haven't any pictures on any of the channels and I take it that you don't have a manual either. You have obviously plugged in a proven aerial lead which you know is connected properly!! On the remote you will have buttons which will allow you to install programs so you need to give this a go first.
I have to say that I assumed that you had a remote that came with the TV and thus it should be coded for that TV so try bobis suggestions. I think you need to make it clearer exactly what you you do have and don't have in order to get a helpful answer.
Hi....we have a remote.. we can pick up one channel that happens to be ITV.....But the TV has been locked for install functions...we cannot tune BBC, Channel 4 or 5
