Please, connect your iMac on an external monitor and tell us if the video output is normal. It's the first step to troubleshoot a screen issue. The issue could be related to a bad GPU (graphic processor unit) located on the logic board or a screen internal component such as LVDS cable or the LCD panel. You can exclude the inverter and backlight failure if your screen still has lightning.
