Very well presented and helpful - thank you.
It sems important to use the correct screwdriver and my impression is that the screws are JIS rather than Philips.
So far I have been unable to locate a replacement screen with back light (I assume the back light is connected by the narrower ribbon cable).
I can’t be sure but think the screws are more likely to be JIS than Philips.
I need the replacement display with backlight and have so far been unable to find one.
