Why is My XPS M1330 showing multi colour and white blank screen

Hi @tolulopeseun Would suggest you to try this step,

  1. Get a monitor / external display.
  2. Connect to your laptop.
  3. You might need to use Fn + F8 to allow projecting to secondary display. If the external display is well, some possible issue which are causing this. Bad LCD panelBad LVDS CableBad Graphic Card
