580 EX Flash Problem

Hi folks,

I had some problems lately with my 580EX, fresh batteries and the flash would not power on for a few seconds. Then it would work... One kind soul in this forum suggested that due to low use the capacitor needed a few flash cycles to re-charge and after trying that it worked.

As of yesterday and after using the flash in day light for fill in it stopped completely and it won't power on at all. I tried different sets of fresh batteries.

Any suggestions what is wrong? Is it expensive to replace the capacitor versus buying a 430 EX MKII? I don't use flash very often.
