Hi, my sigma EF500 super just died on me today (in the middle of a grad photoshoot!). It was working fine, until my friend told me that there's no flash output. After changing fresh batts and testing it out, I think the bulb blew. All other functions/buttons are working fine, and when I press the 'test' button, I can hear a soft 'click' sound but no flash output.
Is it cheap to replace the bulb? I think this flash is still under warranty but I bought it 2nd hand and don't have the receipt. If it is cheap, I thought I'd just bring it to any camera repair shop (like camera workshop?).
Anyone can help me? Thanks.
