First thing I would remove all cables from the projector except the power cord and turn on the projector to see if the lines are still there. If not the interference lines might be caused by bad cables or a defective source. But if you see the lines on the screen even with no cables connected, I would suspect a defective Video main board in the projector. Please let me know.
