Guys, Without the thread I am sure I would have had a chisel and mallet to hand but follow the thread enabled me to replace the Digitizer screen.
Note, To be honest you need not take the Black frame off the LCD, using a craft Kife carefully around the edges of the screen is enough to release the digitizer from the LCD.
Also my 8 screws were of Alan type not Torx but at that size little matters.
All the same thanks for having a go in the first place.
Knees in the breeze
