I have replaced the broken cap with an identical model, but unfortunately the flash head remains dead when connected to power. Tried a new fuse but still the same.

Visually I can't find any defect parts, so not sure what might be the cause. I don't really want to pay for repairs again, because it lasted only two shoots after the last one and I don't want to loose too much money on it.

If anyone might have an idea what could be the issue (there seem to be a lot of experienced veterans on here), I would be grateful for any suggestions.
