My old model canon 350D jus dead not even a blink, I've tried with both batteries, replaced them recharged them, reinstall the CF card and lens replacing, nothing works out
any solution please?!
The main batteries weaken over time. If both batteries are several years old, they may not be able to hold enough charge, even if the charger lights indicate they're charged. Also try replacing the CR2016 button battery that powers the time/date features (p. 38 of the instruction manual).
