Update: I took the phone apart...and found the LED. I plugged in the power and ta-da! The silly thing lit up!

I don't know if perhaps I tightened it when I pressed on it...or if my mom's cataracts are worse than I thought...

Now I get to put it ALL back together again!

But even if I did replace the part - I couldn't see how to separate the small circuit board from the other boards...the ribbon connectors seemed glued on.

Please pray that it still lights up when I get all the bits and pieces back together. My sweetie said I should have tested it before demolishing it! DUH me!
