It seems you assume that it is not an overheating problem.
The problem is, the bulb gets really, really hot when using the projector. It doesn't matter whether it has been there without any usage. As you switch it on, it will start to get hot.
But the lamp or other parts of the projector should not get too hot. To control the temperature, air is moved through the projector with the help of fans. Air enters through air filters and move through the projector absorbing heat from hot parts. This prevents these parts from getting overheated.
But what if air doesn't flow freely? Then the parts CAN get overheated.
First, switch on the projector and check whether you can hear the fans working.
Next, switch off the projector and remove power cable.
After about 30 minutes, remove the cover and check whether the air filters are blocked. If they are, clean them with a small brush.
This would probably solve your problem.

I've seen this happen almost exactly on a Canon projector. The problem was the bulb. After the bulb was replaced the problem went away.

Please remember to rate this solution to show your appreciation!

We found that the bulb was dim because it was about to burn out. The projector's filter han't been kept clean, causing it to run hot, which in turn shortened the bulb's life.

if you know how to open the unit, try fixing its ventilation. flashing bulb light sometimes mean an occurance of overheating. try to clean all the fans and the air vent.

Yupe, you need new lamp. Ouch.
