Laptop Screens are more fragile than you think and crack from the smallest off impacts. Depending on the laptop, we can just replace the screen were as others may need a whole lid assembly. we start by identifying if the screen is LCD or LED by removing the front Bessel on the screen. The screen is unscrewed from the side and removed from the unit, revealing a serial number we use to identify the model off the screen before ordering one to the shop. Once fitted, the unit is left on test for 2-3 hours using a program called OCCT which stresses the graphics off the unit.
