Default Black Screen help please

GT-19100 running OmniROM recent build. Had been working great, today I took it out of my pocket to a black screen. Google searches point me towards Screen of Death and Sleep of Death, but that is not what this is. I can boot into download, recovery, and until I stupidly flashed CWM via Odin, I could even boot normal. Nothing but black screen anywhere. So... hardware failure? adb recognizes device just fine, just no screen.

Also, if its hardware failure, I could recover some files off of internal storage until I tried the Odin trick. With no screen, I can't mount the sdcard in recovery, and can't re-flash the OmniROM zip file. There has to be a way to do this blindly through adb, isn't there?
