I have a kodak pro back plus and the monitor on the back no longer "stablizes" rendering the back unusable without teathering it to a computer. It looks like the screen needs to have "tracking adjustment" like you would expect from a funky VCR input. has anyone else seen this? Can I still have the back serviced? and if the answers to these two questions is no, then does anyone want to buy a really cheap kodak pro back that can now only be operated when teathered? or at least provide me with a gun for suicide.
