Question about Nikon Speedlight SB-600 TTL Flash
I am having a problem with my sb 600. My flash does the weird battery thing, I put the batteries in and it stays off unless I push on the cover. I have to push it just right to get it to stay on. Then when I am firing, the flash will go off sometimes, and then sometimes it won't consecutively, I hit the flash button consecutively and it will go off 5 times and then it won't a couple even though I will wait for the flash to get back to full recovery. It is frusterating when people at a wedding are waiting for you to get it right.
The battery contacts are not making proper contact to the battery, or there is a cold solder connection in the circuit board inside of the flash unit.
There are photo shops that can have flashes serviced, or you can send the flash to the manufacture service department.
Unless you are able to do electronics service and are used to working on high voltage electronics at the component level I don't recommend opening the flash yourself.
Inside the flash they use very high voltage at very high discharge current. Even though the flash looks innocent and works only on a few simple batteries, this can be dangeriously deceiving. The discharge current can be very high, and the main flash capacitor can hold a lethal charge for many days!
