"Digital" is a very vague term for televisions. A telelvision can be called digital if any part of the signal path uses digital data. Therefore, any plasma or LCD telelvision is digital as they all use digital signals in generating an image. The question probably refers to digital inputs. If it has a digital receiver built in, for terrestrial digital broadcasts (UK Freeview, for example) or has a digital cable decoder, then it can be called digital. In these cases, the manual will point out that it is a digital TV. If the television has HDMI or DVI inputs, both of these are digital inputs and it is therefore a "digital" television. A better definition of "digital" in this question would get a better answer.
