Broken SB600, diagnosis?

[MOREGONE]

Hello,

At the last wedding I shot, I started having some intermittent flash issues. Even though the batteries should have been fresh just chalked it up to a battery issue.

Later when looking into it I found it would power on but not pop. So I thought it was the bulb. Left the batteries in it and put it away. Came back the next day powered it up and a couple tests it went off a few times (like every 3rd press and stopped after firing 3 times out of 10 test fires)

So I am thinking it is the capacitor that went bad? Does that right? Does anyone know if it is repairable? I got a replacement for it already so no issue there but it would be cool if I could resurrect it.

My guess would be a connection rather than the capacitor. When capacitor's fail, they generally fail. Full stop. Trouble-shooting intermittent electrical problems, especially in IC/digital devices can be very tricky.

Are the battery contacts in the battery compartment of the flash unit corroded?

Yeah one of the things I read is that the capacitor makes a popping noise. I heard nothing of the sort. I was wondering if it may have overheated. It was a Phoenix afternoon over 100 degrees when it happened. But it was just taken out of the bag

Nothing I can see. It is used routinely and the batteries that came out were fine and still in use (rechargeables)

Thanks for the replies.

I may crack it open and see if I can notice anything with a visual inspection.
