Proview 15inch LCD (Product No)PL482i (Model No) 468P

       This 15inch lcd proview has power issues every time I turn it on, and when it it is pluged in it displays a green light for a few seconds screen flashes then goes black. Now when it is not pluged in a computer the power light displays a white light screen flashes like before then goes black again.
       Please guys if there anything you can do to help I would be very gratefull thanks ;-)

It sounds like the power supply is weak or the wrong one and is shutting down from the load.

Check the input of the LCD with the output of the power supply, if they are the same try a new power supply.
