Prices of screens vary anywhere from $400 to $1200 depending on the model, size of screen. We usually replace just the LCD, however if your screen has backlight issues or if this is an urgent repair/quick replacement inquiry, or new LCD cannot fit in due to dents or excessive damage then the entire display needs to be replaced. We also sometimes may offer used displays to make it more affordable if your casing has issues. Some of the models such as the 14" MacBook Pro third party screen replacement can only work if the LCD is replaced and the original IC chips are transferred from your original LCD to the new one. On some of the models you may lose True Tone feature when display is replaced. If you have any questions, please feel free to get in touch.
