hello guys..
just wondering if anybody experienced this before.

my flash stopped working last night.
LCD, battery, zoom motor
everything works correctly but the flash wouldnt fire.

when turned on, there is a buzzing sound from the flash.
something like electrical sound.. coming from the bottom part of the flash
I bought the flash around 2011ish.
any idea what happened to the flash please? it is time to kaput already?

thank you
