Is it a brick?

Hello!

I just bought a used Nikon N80. It seemed to be in perfect condition, but I took it home and discovered a focusing problem.

The image in the view finder is dim. And when I try to focus, the lens goes in all the way and back out to infinity without finding a focus point.

I tried a few lenses with the same result.

I checked the sensor at the bottom of the chamber, and it's clean.

Like I said, the camera seems to be in great condition otherwise.

What do you think? Is this a brick, or can I fix it?

I should also mention that I bought the camera with the lens improperly attached. I had to carefully cut a tiny piece of plastic off the lens mount to get it off.

Fortunately I paid only $20 for it, plus new batteries.

Thanks for any input on this!
