Hi Matthew
I also tried another battery but without success...:(
The technician replaced the flash board but the problem persists...
It's not related with the mode TTL since I tried with the other modes (P, A, M..)
The technician after replacing the flash board said that flash worked for few times and stopped working again...
The problem is this:
When the battery out for many hours and insert it I was able to use the flash for 4 photos.
- I insert the battery, turn on the machine and go to a dark place.
- In the first shot the flash pops up and works fine.
- then I shot more 2/3 photos with flash
- after that the flash don't work no more... (it's also not bad contact)
I thought the problem was solved the first time I leave the battery out the machine during the night.... but not.
Now I'm afraid it's a problem on the motherboard, because I do not know if the motherboard has or does not influence on the flash.
Many thanks
