Hi @soumitrodas

Try connecting an external monitor to the laptop's DP or vga port and check the display on it coming from the laptop. Don't forget to press the Fn + F4 keys (both together) to switch the display from external only, to laptop only to both on together.

If the external monitor display is OK then most like there problem is in the laptop screen. This cannot be repaired. The screen will have to be replaced.

Here's the maintenance and service guide for the laptop.

Go to p.76 to view the procedure to remove the display assembly.

On p.79 it shows how to remove the LCD panel in the display assembly. It also shows the part numbers for the 3 different LCD panels that can be used in the model i.e. HD 1280 x 720, FHD 1920 x 1080 and QHD 2560 x 1440 resolution.

Search online for the appropriate to your model variant part number only to find suppliers that suit you best. Usually the part number is somewhere on the back of the panel, if you wish to verify which one you have.
