My Dell Latitude screen just went black [closed]

The backlight is off. Others are probably right that it died, but try fiddling with your brightness controls first. I've had laptops where something happened and the brightness controls would actually allow you to turn the backlight off while not disabling the display.

"I recently had the very same thing happen.

My local shop replaced the inverter ($20) and all is well.

It may be the same thing."
