Ah. A HYPOTHETICAL question! The pop MAY have been a bulb. The connectors are close on PCs. Do the whole rinse, dry out thing, and see if you can then borrow a bulb to try (once it's clean AND dry, you shouldn't hurt a bulb). Now that I think about it, about a month ago I took a 48" PC fixture I have on my big fuge, and opened it up and dunked it to get rid of the salt creep. I let it dry for about 2 days. Never even considered that it might not function again, just assumed it would.
