Hiya, first post. I have a camera flash. A nissin Di622 to be exact. I have now spent nearly 12 hours trying to diagnose it. Everything appears to work but the main capacitor is not charging. It registers 6VDC. On one of the boards there are two transistors mounted on either side of the boards switching the 6volts onto a big ish transformer. I have compared the faulty unit with my other that works fine. I can't measure anything that is different. Just that the faulty one never looses the 6 volt i/p to the transformer. The good one switches it off when charged. The main capacitor measures 1400uF as it should, and should have a 330v feed.
Does anyone have experience of diagnosing this. I don't mind admitting I am in over my head here.
Thanks in advance for my advice.
