It will actually be more work to remove the screen and lid completely than it will be to just fit a new screen panel. This model looks easy to fit a new panel in, it can be done without removing the lid
If you really really want to remove the lid completely then it involves taking the keyboard out to get at the connecting leads, and removal of the wireless ariel as that runs round the lid (as does the bluetooth ariel if fitted). And one removed it can be a PITA getting the hinges realigned properly.
Just do it properly and fit a screen. Its probably cheaper than you thought as well
