I have a Media Centre PC incorporating a TV tuner. I bought the PC just before Christmas but having moved house have only just got around to hooking it all up to its various facilities. I have a roof aerial connection in this room and have plugged the antenna into my PC and run the Media Centre TV set up. It has recognised my terrestrial channels and configured them, but I cannot view any of them. The channel shows up on screen together with confirmation of the programme airing at the time, but there is no visual and the only sound is static hiss. The PC is an HP m7635.uk. I should warn that I am an unsophisticated home PC user and not in the least bit techy so jargon confuses me! If anyone can point me to some simple options to try or some sort of diagnostic I would be most grateful

I have to confess to not knowing much about TV tuners other than that they're not all they're cracked up to be! The one thing that I do know that some people don't consider is that some TV tuners are analogue and some are digital. Analogue tuners will only display analogue transmissions and digital tuners will only transmit digitally-received stations. If you're connecting it directly to a cable from the roof aerial and using good old-fashioned analogue TV rather than digital via cable or satellite, is it an analogue tuner?

I hadn't thought of that. Yes, it is an analogue connection. I have satellite but it's not accessible from the room that my PC is set up in. I just figured it would be useful to be able to view the few terrestrial channels that are available without the rigmarole of getting a digital receiver installed in this room. If I invested in a Freeview receiver do you think that would solve the problem?

Many TV tuner cards are capable of wordwide broadcast standards. In your case, you may need to set the signal format for your region. Please refer to the map in the bottom of the page below to verify the format chosen for your region in your TV adapter card-Thanks

For most Europe, PAL is the fromat.
