LG Optimus V Black Screen Fix

I have an LG Optimus V that I use for testing. Its battery had run down and when I plugged it back in, the buttons would light up but the screen was black. So what to do with a blank screen? Unplug from wall. Remove the back cover. Remove the battery. Put the battery back. Replace cover. Plug it back in. The screen is back!
