Yes, they are screws you're not going to find at the hardware store. Go to a camera store & they'll fix you right up. Yes, those screws do come loose. It really shouldn't cost much + its a good idea to keep your camera together.
Replacing a damaged laptop LCD screen can bring your laptop back to life.
You'll be able to access files you thought were lost and use the laptop just as you did before. And it's not as difficult as you might think.
Turn off the power, unplug the battery and all cables.
Eject the installed battery if you have one.
This will protect you against electric shock.
Find the small, round rubber screw covers and pry them off.
This will expose the small screws holding the LCD screen frame in place.
Depending on your laptop, these covers might be made of some other type of material.
Remove the frame by gently prying.
Locate the LCD screen's cable and power supply cords. Unplug them and remove any tape holding the screen in place.
Check the identify of the manufacturer on the back or side of the screen.
It may be different than your computer's manufacturer.
Since these screens look so similar, make sure you order an LCD screen that matches your manufacturer's model number, or else the new screen will not fit.
Plug in the new LCD screen, replace any tape holding the screen in place and replace the frame.
Don't pinch any wires as you press the frame back into place.
Screw the frame down and switch on the power to see if it works.
If it does, go ahead and replace the screw covers.
If it doesn't, remove the battery, the screws and the frame.
Check your connections.
If it still doesn't work, call your parts supplier and ask for assistance in getting another replacement LCD screen.
Hope this helps
