You can check inside or at bottom if there is any fuse box because your fuse might have gone..

Hope this helps.

We recently had the same problem with our church projector and we too had just changed the lamp. I read somewhere while searching for an answer that if the cable input is loose it will cause double vision of the text. Sure enough, the cable was loose and after tightening the text cleared up immediatly.

Hi there

There should be a lamp door at the bottom of the Projector that you have to unscrew before you will be able to take out the lamp.
