If not, (zero volts or whatever) then go back and recheck your blue wire repair, since the last thing that got fiddled with is usually the first suspect :)
BTW that burnt blue wire may have come in contact with the white ground at some point--and note that the entire metal box all that comes in is a "live" ground so it can touch almost anywhere for that to happen.
