This wasn't in my Readers Digest Fix-everything-in-your-home book, so I came to PT!

My mom gave me her phone/answering machine combo. It's under 3 yrs old, and works well - but the light that shows how many messages one has has gone out. It's an LED display, or something like it.

I am happy to take the thing apart - but what should I be looking for?

It's perfect to donate, but not with that light blacked out!

Thanks.
