41c clear plastic display window

[Johnboy]

Hi all, I have a 41C full nut with cracked a display window, and I have donor calculator ready to swap the window with.

I realise the LCD display needs to come out to do this, but does anyone have any experience and suggestion on how to remove the display window without damaging it or the calculator case ?

It might depend on whether it's glued in (I don't think it is), or maybe plastic welded/heated etc which make it more difficult to remove.

Any suggestions would be appreciated.

Thanks
John
