Have to announce that my SB3000 is dead.
Can power on, red 'ready' light comes on faster than usual, lightning symbol appears in viewfinder, but the flash does not fire when shutter is pressed nor when the test button is pressed. Charging sound has not changed, it just stopped firing without any warning.
Before this the flash sometimes would not go 'ready' and I had to repeatedly switch off and on again before it will register as 'ready', so maybe that was a warning sign already.
I rmb when I bought the guy said 'Export set no warranty', so I guess I will have to treat it as a write-off?
