Canon T50 repair & common faults
Excellent coverageThe T50, launched in 1983, was Canon's first fully automated FD-mount body, built for beginners who wanted point-and-shoot simplicity from an SLR. It has no manual or shutter-priority mode at all, running Program AE exclusively, and drives film with a built-in motor rather than a thumb lever. Everything, metering included, depends on power from four AA cells.

Common Canon T50 faults
Canon T50 completely dead, won't wind or fire
This is the T50's signature failure. Because the body has no mechanical fallback, everything, meter, shutter and wind motor, needs clean power to work at all. Corrosion on the AA contacts is the usual cause, sometimes from cells left in over a long storage spell. Worth trying a fresh set of batteries first, but persistent dead silence usually means the contacts or wiring need proper attention.
Canon T50 motor won't advance the film
A shutter that fires but leaves the frame counter stuck points to the wind motor or its gear train rather than the shutter itself. These motors have done tens of thousands of cycles on a forty-year-old camera and wear is common, as is a slipping clutch. Confirm the battery compartment is clean and the cells are fresh before assuming the motor itself has failed.
Canon T50 exposures come out wrong
Since there is no manual override to fall back on, a consistent over or underexposure trend across a whole roll points straight at the metering circuit or its SPC cell rather than technique. Age can drift the meter's calibration even when it still reads and responds normally. Check nothing is covering the meter window before assuming a fault, but a genuine drift needs the circuit looked at.
Canon T50 viewfinder shows no meter reading
A blank or unresponsive viewfinder display usually means the meter circuit isn't getting power or isn't completing its reading, rather than a shutter problem. On this body that almost always traces back to the battery contacts or the switch that wakes the metering system on a half-press. Fresh, correctly seated batteries rule out the simplest cause before anything is opened up.
Canon T50 shutter sounds rough or sticks
A shutter that hesitates, drags or sounds different from one frame to the next is usually down to old foam and lubricants breaking down inside a body of this age, which affects the timing and travel of the vertical metal curtains. It rarely gets better on its own and tends to worsen gradually rather than fail outright, so it is worth having looked at before it strands a roll.
