I'm a landscape/garden photographer, so I seldom use my flash. Since, however, I'm going out on a job that might call for some fill, I got out my flash to check the batteries. You can probably guess the rest of the story. The batteries had all gone south, leaving a nice acid crust on the contacts. I've scraped the contacts, run an emery board over them, and swabbed them with a vinegar-soaked q-tip. The flash still won't come on. Any suggestions?
If it's an expensive flash it might be worth sending in for an evaluation to be fixed.
If you are electronically minded, you could try fixing it yourself.
