Shoot, hadn't considered you tested it with the ring out - but that's exactly what I did a few years back (forgot). Threw me for a loop.
Every once in a while it won't come on and I have to giggle with the ring. Glad I remembered to tell you about the ring grounding. I love an easy solution!

Ok after reading your post I went back out and put replacement bulb in, then refitted the ring. IT WORKS!
I didn't refit the ring before, so no ground, no workey......
Thanks for all the help!
