One assumes you are talking about the mains lead. What shape is the connector on the TV?
This is common. It is generally referred to as an "IEC" connector. Here's a 3 metre lead, although they are freely available in different lengths.
Right angle, to save space behind:

The other type it could be is often called a "Figure 8 connector". Here's a typical one:

Its vaguely possible the TV has a "Cloverleaf" connector. Here's a typical lead:

But I do have to agree with the other comments; its a bit pathetic that you couldn't e ven search for "mains lead" and look at the pictures. Learn how to use Google, for heavens sake!
