SUMMARY
Many "broken" film cameras are simply stuck due to old grease or minor issues. Simple DIY fixes include cleaning battery corrosion with vinegar and isopropyl alcohol, replacing light seals with pre-cut kits, and exercising sluggish shutters by firing them repeatedly. For more complex internal shutter or focusing mechanism problems, professional Clean, Lubricate, and Adjust (CLA) service is recommended. Given the rising cost of film and processing, a professional CLA can be a cost-effective investment to ensure accurate exposures and prevent wasted film.
