A: For Sigma issue:
The Sigma EF-500 flashes have very small chromed contacts for the batteries. Even though they may not look corroded, they may not power up or conduct enough power to fully cycle up. Use a polishing tip in a dremel or an ink eraser tip to clean the internal wire contacts and the flat contacts on the door. I use dielectric grease on a q-tip to apply a coat to all contacts and cleaned battery terminals to minimise future issues.

Thank you for using FixYa for your problem
Always check the batteries first - make sure they have full charge (in the wrong way can discharge them) but if is it still giving the same fault, your flash is faulty.
It should be taken to an authorized repair centre for a repair estimate. Very few digital cameras have any user-serviceable parts.
