the warranty on Sim2 projectors is 2yrs.
They also have a 3000 hr or 1 yr warranty on the lamp, whichever comes first.
Make sure the Denon is not set to Enhanced in the menu as this can result in a green picture.
Sometimes components connected to each other digitally don't "shake hands" with each other properly. If this happens it's best to put the DVD player in standby and then power it up again with the projector still on and the digital input selected.
