I just did a flash sync problem OM-4 that, at first, seemed to be IC
oriented. After pulling the front casting out to get B working, cleaning
the X contact, scraping the safety switch clean, and resoldering many
contacts, x and TTL flash came back to life.
So, while many OM-4 problems can be fixed, some can't, economically.
