Ok, that's huge, thank you. So now my camera is in external flash
mode. I am now starting to wonder if my flash is simply not
working; I bought it used on ebay. I have my camera in aperture
mode, and in external flash mode, and the 285hv turned to the ON
position. The flash is sitting in the locked position in the hot
shoe, which has a good connection. I have turned it on, let it sit
there for about a minute, and the green light never come on. Unless
there is something that I'm missing, maybe there's something about
the flash I don't understand, but can I assume that I received a
DOA?
Not necessarily...
From what I have read and my personal experience with my Vivitar 283 (smaller sibling of your 285) this is not unheard of with these units if they have not been used for some time.
First, though, does your flash fire when you use the manual firing (test) button? If it does then check camera settings and hotshoe connection.
If it does not fire using the test button here are some things to try - in sequence:
1. Make sure you are using batteries
known to be good.
2. Check that the batteries are all inserted the correct way round. (Yes, yes, I know, but it's amazing how often these things happen - even to me! ;-0 )
3. Check that
all battery/battery-clip connections are clean. Just for good measure clean them anyway. A pencil eraser is good for this, but make sure you blow out all the bits when you're done. If you see any corrosion anywhere you'll have to clean a little more... er... thoroughly.
4. Using
fully charged batteries (or, better still, a mains adapter if you have one), switch the unit on and leave it on for a while (I've seen an hour or so suggested). I'd suggest you check periodically that nothing is overheating during this time.
Try the flash again.
5. If still no good, repeat step 4 (remember the fully charhged batteries bit) - perhaps a number of times (I've seen 3 or 4 times suggested to be necessary with some units).
With luck your unit will start to work at some point in the above process. When it does (fingers crossed...) it's a good idea to 'form the capacitor' in the following way:
1. Switch the unit on and allow to charge fully - let the ready light stay on for 15-20 seconds.
2. Fire the flash
at full power using the button on the unit.
3. Allow to recharge and wait 15-20 seconds again after the ready light shows. Fire again at full power.
Repeat step 3 until you have fired the flash 5 or 6 times.
Job done - though it's a good idea to form the capacitor every so often, especially if you have not used the unit for some time.
I hope this helps, Mike, and that you get your flash working. It would certainly be useful over the coming festive whatsit.
Have a good one,
Cheers,
