I'm not getting the right amount of t.v channels I'm meant to be getting?

Read the instruction book that came with the set and go carefully through the tuning procedure. If you have gone through the instructions exactly the set may be faulty. If you bought it from a local retailer visit to get them to talk you through the set up. If then it appears that you have carried it out correctly you will have to return the set under guarantee. If you are getting a reasonable picture on ogue you will get digital channels with no problem.
