Its Power on but gives display sometimes and sometimes not give display
Hi, Connect an external monitor and check if it shows a display OK. Also when the laptop screen shows no display, use a torch and shine it at an angle close to the screen and check if you can detect a display at all. It will be very faint so perhaps it will be easier if you try this in a darkened room
try to open it up and disconnect the screen then clean the screen connectors with alcohol assembleitup and retry
