Sanyo plv z2000 warning led it shutdown

I have watched almost 2 movies on the projector. And in sudden the projector shut off by itself and give on top of the projector a Warning Red Light. I read the manual what to do. it says to pull out the powerplug and replug it. After press power button... then it happens again it shut down and give warning red light. (i let it cool off already). I hear strange noise when it comes on... 4 little rotation sound or some kind. I already cleaned the filter and blow under the beamer in the holes that is indicated for cleaning. So what can i do? i never had this issue before after watching several hours on it. it just happen a few days ago. I bought this beamer date 22 july 2008. Hopefully you know how to proceede. thanks.
