Generally, yes. Screens can be a bit expensive though, but usually its just a matter of fitting the ribbon cable to the base of the laptop and screwing it to the hinges. I do have a dell though, not a Sony. Knowing Sony they have some ridiculously hard routine for fitting a new screen. On my dell, there are only actually 3 points of contact. The two hinges and the ribbon cable. The hinges are literally screwed in, and the ribbon cable clips just under the keyboard. But thats only because it comes with the bezel already fitted. If you get a screen on its bare own, then someone with technical knowledge of a sony will need to help you there mate. Sorry i cant be of anymore help.
