Epson TW-3500 lamp problem (see video)

Hi,
today my 2.5 year old projector (1200 lamp hours) suddenly switched off the lamp and continued without light with higher fan noise and red lamp LED flashing.

When I switch off/on the projector (http://youtu.be/dEFNUwCXol0) I can hear ,,buuuzzz'' sound followed by the red lamp icon flashing. Is it lamp or lamp ignition problem?

Thanks

P.S.: 6 months ago I had the similar problem, lamp was ok but the ignition unit had to be replaced.

Problem was caused by broken (dead) lamp unfortunately.
I had to sent projector to Epson service and lamp was replaced by the new one within 3 years lamp warranty for free.
