If something ran down the lens, then adjusting the focus should cause a visible change on how the lines are projected. Also, to me the lines look too regular to be anything physical inside the lens. What is much more common is issues caused by poor contact anywhere between the image processing board and the SXRD (LCD) panels or, worse yet, an issue with the image processing board itself. The lamp is not the issue for sure. So, the only (slight) hope other than spending too much money is to disconnect and reconnect those inner cables, but there's the chance it will get worse, and it's nothing you should do unless you're confident about disassembling a complex projector. Also, I may be wrong. I say you should sell it as defective and look for a new one.
