When i replaced my lcd completely then also my problem is not solved. ones the laptop started after 2to 3minutes screen will goes very dim. Sometimes it is automatically goes off. I checked the inverter and the backlight but I cannot understands the problems. When it connects to an external monitor it will be just fine. What will be the problem occurred in this case please give any solution.
