When awoken from sleep my MB Air shows a blue grey screen initially with some vertical lines through the middle portion - when restarted the same problems occurs - I have done a PRAM and SMC reset a few times but there is no change other than now the lines on the screen have increased considerably and are both vertical and horizontal and I have no further access on to the machine - advice as to my problem and how to deal with it would be much appreciated

Have you tried an nvram reset?
The screen issue may be due to a loose LVDS cable, MacBook has been dropped, or exposed to liquid.
I don't think it's a software issue if that's how it looks as soon as it is powered up.

Thank you Lee
When I reduce the screen dimming , through the lines , I can just about see the login page and if I have enter the login password it opens the computer - this , with my limited knowledge , suggests some type of display problem.
Any further thoughts on how to deal with this ?

Are a NVRAM and PRAM the same thing ? If so I have already tried PRAM a few times

PRAM and NVRAM are the silimar: https://support.apple.com/en-ca/HT204063
Since you have tried the hardware reset, you need to check for a loose cable, re-install the OS, or signs on damage. Based on what I see, the Air needs a new display.
