Ricoh 500 repair & common faults
Fair coverageThe Ricoh 500 is a fully mechanical 35mm rangefinder from Ricoh's late 1950s line, built with a leaf shutter that needs no battery to fire. Its exposure meter is a selenium cell rather than an electronic one, and it is the ageing of that cell, alongside the shutter's own lubricants, that decides how well a given example still performs.

Common Ricoh 500 faults
Ricoh 500 light meter reads wrong or needle won't move
This camera's meter is a selenium cell, self-powered rather than battery-driven, so a dead or sluggish needle points to the cell itself fading with age and light exposure rather than anything you can swap in. Covering then uncovering the meter window will show whether the needle responds at all. A weak or flat response usually means the cell has reached the end of its working life.
Ricoh 500 shutter won't fire
Usually old grease inside the leaf shutter has thickened and is holding the blades shut, or the shutter simply hasn't been cocked because the film wind is jammed. Worth checking the wind lever has completed its full stroke before assuming the shutter itself is at fault. If it still won't release, the shutter mechanism needs attention rather than the film transport.
Ricoh 500 slow shutter speeds hang or sound uneven
On a shutter this age, the slower speeds are usually the first to suffer because their timing depends on a delay mechanism packed with lubricant that thickens over the decades. Fast speeds can still sound crisp while the slower settings drag or hang open entirely. It is a mechanical timing fault, not a sign of wider damage, and is one of the more common issues on a camera like this.
Ricoh 500 rangefinder image is faint or doubled
A weak, discoloured or doubled rangefinder patch usually comes down to the internal mirror or beamsplitter losing its silvering with age, which is common on cameras from this period regardless of how carefully they were stored. It affects focusing accuracy rather than the shutter or meter, so the rest of the camera can otherwise be sound. There is nothing to check without opening it up.
Ricoh 500 film wind or frame counter won't advance
A stiff or jammed wind lever, or a frame counter that stalls or fails to reset when the back is opened, points to wear or dried lubricant in the film transport gearing rather than anything electrical, since this camera has none. Confirm the back is fully closed and latched, as a loose door can itself stop the wind from turning. Persistent sticking beyond that points to a transport fault.
