Hey guys, I have a JBL BoomBox never had a problem with it until a few days ago! My speaker died so I plugged it in, and it started blinking red I thought it was just super dead so I left it on the charger, but with previous encounter it still blinked white indicting it is charging, this time while on the charger it is blinking red, it has been on the charger for 2 days now and still blinking red, i dont know what to do about this i have contacted jbl and i dont have my recipt or box in that matter
