Hi I have a Acer Aspire V5-571 laptop and I ordered a screen listed as working with Acer Aspire V5-571 V5-571P models and when I went to to hook it up it only has a 30pin cable not 40. I saw some cable since I was going from lcd to LED screen, but not sure what type of cable I would need to convert it over to the 40.
 
on both screens look up the service part number then you have to look up the service part number for the backlight/power board. if your lucky the display cable from the system boards are the same. you should be able to google the laptop modeles and service parts to see if there the same.
