^^ A fast blinking light (ie. 2x/sec) would indicate either a loose speaker wire from one post touching another post or maybe amp failure while a slower blinking (ie. once/2 secs) would be a ventilation issue. Is the unit hotter than normal to the touch? As I suggested in my previous post, if you purchased from an authorized dealer and used a credit card, check with the card issuer to see if they will add a 4th year of warranty if you need to go that route.
