As iitywybmad so cleverly found out, my problem was also the little diode. For reference, the original one says "4007" but I could not find this anywhere. I got a 4005 from RadioShack and went to my local audio/electronics shop to get this installed. He had done some expensive work for me in the past so he did this one for free -- it took him about 5 minutes including testing it.

To get the light out, I employed my daughter who is an engineering student and very flexible. She spent maybe 30 minutes getting it out (yes that second screw is a bear). When we tried to reinstall the next week the screws were nowhere to be found (typical in our home) so she used duct tape and the reinstall took her 15 minutes.

Thanks to iitywybmad for his great discovery! Saved me considerable $$$.
