Unfortunately, it is true that the replacement part is unavailable as it was specifically from Olympus. My years of research on this issue, also, has not turned up any 3rd party repair options. If the part could be found, judging from general market values it would cost at least $95, putting the repair at over$150. Considering the age and present value of this camera, paying the cost of having it repaired , approximately $150 really depends on how attached to the camera you are, but is not very cost effective. The standard "rule of thumb" is if the repair cost is greater than 50% of the value of the camera, it is not worth it. A used Olympus stylus 850sw can be purchased for about $45-$85 online.
In addition a Class Action Lawsuit was filed against Olympus concerning this specific issue. While I do no know the current status, the information at the link below may be of interest.
Please keep in mind that my diagnosis & solutions provided are directly
dependent on the accuracy of your description of the problem. As with
any "do it yourself" fixes, success is a "team effort", since I can't
see or touch the camera, and relies on the customer's manual dexterity
and ability to follow the instructions well.
