Chris,
It was actually quite straight forward, just a bit fiddly. It cost me £25 all in for a new screen and special 3 point screwdriver.
I had to sus out how the ribbon cables were fixed to the circuit board, once I had done that, as I say it was not too bad.
I got the screen from a firm in Devon. Placed the order Friday morning, it arrived with the postman Saturday morning. They do a repair service as well. If you want the details I'll forward them.
Cheers
Colin
