"Some months ago I dropped my favorite Fluke multimeter flat on it's face. It died. I took it all apart, poked and prodded and eyeballed it all up---no joy. Still dead. With a heavy heart I set it aside. They are no longer made and the modern model is pretty costly."
Send it to Fluke. For a flat rate fee a fraction of new cost, they will rebuilt it, update it and send it back like new. A major reason pros buy Fluke.
