A common problem is the corrosion of the contacts inside the holes on
top of the 1n/2n. This is caused by the decomposing foam that sits
between the flash bracket and the prism.
You can try to clean them but the contacts are so light (little tension)
that you almost can't tell when your touching them with that sharp
scraping tool. Then, even if you DID clean them, they're bent so far
down that the shoe pins don't touch them anymore.
