On Sony Vaio laptops generally the only way to locate the correct screen for your laptop is to actually remove the screen and use the screens part number on the back of the screen. Sony use different screens in just one model of laptop, and most of the time only the one will work with your motherboard and components, so be careful! It needs to be swapped like for like!

The screen number that you are actually looking for will vary depending on the screen make, but it will almost always have the screen size within the screen number. For example if it is a 15.6” laptop screen, the model number can be LTD156AW01.
