Did u fix it? I know when the fan speeds up its in the overheat mode and on earlier models the 2 lights also mean overheating..was it left in an area that lots of dust gets to? Overheating is cause by bad air circulation or blown capacitor.If u had no problems with it last time.its probable the capacitor os still good,unless others have played it without u knowing. So most likely its ir flow problems.possibly a cat or dog that sheds alot camped out by it for a bit.i keep hearing to use a can of air and ..NO...dont ..for obvious reasons.if u have a small vaccuum with a hose that suctions out put that up against the air holes.using an air can only pushes yhe dust in further into the system and making it even more suseptible to overheating and possibly blowing a capacitor or startung a fire
