I had a brand new Wahl Bravura that I had forgotten I had stored (for months). Anyhow when I went to charge it, I can only get a flashing battery symbol. The symbol does show that it has charged, but when I remove it from the charging stand I get nothing. I tried running it off the power cord, still nothing. I have never had a Bravura that is completely "dead," so I have no idea what to do. At this point I can't even tell if I have the unit turned on or not because it will not even chug a tiny bit. Any suggestions?
