Hi everyone, recently been having an issue with my Dell Studio 1537, when I push the lid back the screen goes very dark, if I shine a light on it a can just about see what's on the screen, if I move the screen towards me again it flickers back on. I thought it might be an issue with the backlight inverter or a loose connection of some sort but its been tricky pinning down exactly what it is but it does seem to be sensitive to movement, can a failing backlight inverter work intermittently like this?
