As far as I aware Sinclair is correct, Iv'e never tuned one in, I just attempt to repair the boards. Our testers do the functional tests, the Freeview section is known to fail, a lot in fact, if you want a tuner I can post you one, they are easy to change. I have a Leister heat gun, I don't recommend a paint stripper heat gun, the print is fine. But with the proper gun the tuner falls out.
