Is the line in the absolute middle of the screen, or slightly to one side or the other?

Is the line one colour or a mix of colours - or black?

I do not have service information for that model (I'm in the US), but can probably give you and idea if you can provide answers to those questions.

it is ever so slightly to the right and is all one colour .more a green than a blue but is very thin probably the size of a pixel

If it is slightly off center, this could be a scan (address) card problem, and it can be repaired. The circuit board is replaced. Some models have two address cards, others have three. They run about $125 (US) plus labor for replacement. Also, if there is some color variance in the line - the Y-sustain board may cause this, more expensive to repair as the board is also replaced (about $350).

However, it could be the plasma display. Although the Plasma display can be replaced, it is cost prohibitive, a replacement Plasma display would run 2-3x the cost of a new TV.

From your description, I strongly suspect it is the plasma display. Sorry it is not good news.
