Lcd Screen Hinges

Dell inspiron 5000e Lcd Screen Problem?
The screen on my Dell laptop sometimes dims. You can still see the icons (barely), but it’s like someone reduced a 100 watt bulb in a room to 2 watts.
I found that when I press on the middle joint of the three (the other two being the hinges), the screen returns to full brightness, so it seems that something might be loose in there. Is this something that I can repair myself? Can anyone direct me to online instructions?
Thanks!
