No. With very rare exceptions, all TVs can be converted to digital with a digital box - even black and white ones.

If your television was manufactured after 1996, it will have a Scart socket. This means it can be connected to a digital box with a Scart lead, which is the best quality connection.

If your TV does not have a Scart socket on the back, and has only a small round aerial socket instead, you can still adapt it for digital. Just make sure you ask your retailer for a digital box with an "RF modulator" built in. This means the box can be plugged into the small aerial socket without the need for a Scart lead (please note that the signal with an RF through-loop or RF modulator will not be as good as the one through a Scart socket). These typically start at about £25. Check a price comparison site such as www.pricerunner.co.uk for the best deals.

Unfortunately if your television does not have either of these inputs it cannot be converted to receive digital television.
