How do we repair a pretty large black solid circle on LCD screen of laptop or else ?
The black circle diameter is ~ 17 mm. What amazing is it is really a perfect circle not the other as people have often reported on such issue as an undetermined shape

Any useful guide will be appreciated

Likely the Liquid Crystal (viscous liquid) section of the panel ruptured and liquid moved enough to no longer react to the voltage controller, or humidity/oxygen is infiltrating the Liquid Crystal layer and that is causing the liquid crystal not to respond to the control voltage. Either way, you'll need a new display or an external monitor.
