Black Screen of Death (3g)

Hey guys, got a problem that i couldnt find using the search function.





Basically, my phone just turned to a black screen and i cant do anything to get it back to normal. This has happened to me once before about a month ago.





I try hooking it up to a power source and nothing happens. The phone makes a noise to acknowledge the connection, but no screen is visible. I tried doing a hard shut down, but that doesnt seem to do anything.





Has anyone experienced this before? How do i remedy this?
