1 - 4 horas
The laptop at some point fell from a surface on my external hard drive, resulting on a cracking screen. Obviously had to be replaced.
It went OK, if you don't mind some screws been to much tight to be able to remove them. It took several hours to replace, only because I had to try different methods of removing that *!&*^#% bezel in the middle - the screws holding it in place were the tight ones. Otherwise you don't need more than 1 or 2 hours.
There is a way to quickly replace the LCD without taking apart the main body of the laptop - there is also a way to connect the LCD cable to the inverter without removing the bezel, but that's too difficult, you have to know what you are doing.
In the case that you want to see what you are connecting, you can remove the bezel only - you can see how in some youtube video.
The third choice (and all that only for the bezel) is to remove the keyboard and unscrew the parts that hold the screen together. In my case those screws couldn't be removed, so I just took of the bezel by removing a very small plastic part on the side of the bezel.
-if there are screws that are too tight, and you don't have some kind of automated screwdriver that can work on them, don't waste your time on them - find a detour.
-if it is just the LCD, all the work is around the bezel in the middle
- and the sticky grey parts when you want to put back the screen bezel
(oh these bezels!)
