Definatly check your cabeling, i purchased a cable from kvant and the interlock pins were not shorted ( as they do this internally on thier projectors i believe) this caused me some problem initally as i have crap rgb from china an had a similar issue to what you mention.

Som projectors will not work if the correct pins are not shorted as per the ILDA spec.
