First disconnect signal cable and power on see whether"NO SIGNAL CHECK SIGNAL CABLE" massage comes on screen if massage comes then lcd is ok if not then monitor is faulty then disconnect ram and listen a beep a contineus beep should be heard then ram is faulty if no beep heard then motherboard is faulty
