1. I have a projector that is putting vertical lines on the screen and I can not find the solution to this problem.  Anyone out there familiar with this problem?

2. I have two other 1209S projectors that as soon as I put in new bulbs they blew out again at $140 each.  I am afraid to try another bulb at that cost, any ideas?

3.  Have we bought inferior quality projectors (1209S)?
