PS: I've just tried to find a date on the manual I looked at online, for an indication of how old your TV set is. On the back page it says 'Printed 95/12'.
If that means that your telly dates from around a quarter of a century ago, it was made before the changeover from analogue TV to digital. If so, it's ONLY got an analogue tuner inside it and is therefore completely REDUNDANT as a 'proper' TV. i.e. if you don't use it with a digibox, and simply plug an aerial into the relevant socket on the TV, it WON'T be able to find any channels when it scans for them, as all analogue transmitters were SWITCHED OFF by October 2012.
However it can still function as a 'monitor', for displaying the output from a digibox (or other external device, such as a DVD player), as per my post above.
