Benq W1200 - new lamp, only greens

Hi Guys,
After almost 2 years my lamp died so i ordered on eBay a replacement bulb (no casing).

After whole operation when i switched on the projector it started ok, displaying the Benq purple logo but when got the signal from my laptop(computer connection, no hdmi) there are only greenish kind of colours, no red, no white etc...

Would it mean that there is something wrong with the new lamp? What else should i check?
Nothing has changed in my setup. I don't know much about projectors but weird thing to me is that the Benq logo gets displayed correctly during a startup...

Any help would be much appreciated...

Thanks,
Lukasz

Did your old lamp explode, there might be loose glass in the color wheel. Your problem sounds like color wheel related.
