I'm telling you... It is not software related... All three things (OS, Download, and recovery) display absolutely nothing it is a hardware failure.
Here is what I want you to do. Turn the device on to any mode. Then shine a flashlight onto the screen. See if you can see any image. If so, the back lights are faulty, if not, you may see hairline cracks in the LCD. If this is the case, you will need to replace the LCD/Digitizer assembly.
Bottom line, it is not a software related issue.
