I have an InFocus X1a and just recently turned it on and noticed a vertical stripe on the right side. Its never happened before. I will try to include a picture. Bulb has 753 hours on it. Any help will be apprieciated.
That looks like a physical obstruction of the light path to me (I'm no expert on this model though).
