I hadn't turned on my projector for 6 months, and now when I turn it on it doesn't focus and is fuzzy, even though I had a new bulb put in a few months before I stopped using it.  Besides wiping down the lense, is there anything else I can do at home to get a better and clearer pic?  

Any recommendations for a shop that can give it some decent maintenance?

Are you sure you have focussed it properly and that the source is in the correct resolution and with a decent cable?

I'd try these before handing my projector over to anyone for maintenance.

dials on the side for zoom and focus? maybe these options on the remote? maybe it's on auto focus but its calibration is off?

I Have a Sony projector and the picture quality is not what it once was. Do I need to replace the whole lamp or just the bulb? Or are they one in the same?

Also, where do I find the replacement Lamp/bulb?

I have never adjusted or refocused the camera when it was idle, however I have checked the focus and that's not it.  It's got to be the lens, so I guess I'll get some camera lens cleaner and see what that does.
