Hi, I have an old Olympus DSLR and it's sensor shows one line of blue streak only in higher ISO 800 and above, I am thinking to replace the sensor. May I know from the experts here where should I go to get the sensor replaced? Understand it may also be possible to replace with other sensor i.e. Kodak ones too (read from DPreview). I love the color of the camera thus would like to keep it in pristine condition as much as possible. Thanks. Cheers.
