How much for Inside lens replacement

I think there is dirt behind the inside camera lens and it maybe scratched. What is the cost to replace the inside lens on a minolta x-700

Lbowermaster@bellsouth.net just to be clear you are talking about the separate lens, not the camera? Do you have any information on the lens? Anything written on it?

I'm not sure if I understand right, you have a dirty Minolta lens?

Is there dust on your matte focusing screen?

Is there dust on your view finder?
