Hi, I have a problem. I ordered a used Sharp projector in Ebay and I was out of the country for 3 months. The projector arrived at my mom's house. When I came back to the States I turned on the projector and saw that there was a big line shadow verticaly accross the screen. It is very unnoticible with a dark image but when you have a white background you can see it. The lamp is new...Its only 300 hours in ecomode and it last 3500. I cannot return the projector because my time to return it is up so I have to do something with it. I wanted to know if there is any way to fix this. I will add a picture so you can understand what I am talking about. Thanks.
