A common problem with Fluke 8010A, 8012A, and 8050A bench/portable DMMs is the LCD will ‘bleed’ or turn completely dark. Replacements are hard to come by. But if some common 7-segment LCD displays are hacked in, you get a meter that can be read in the dark.
I did this project before starting this blog and did not fully photo-document the process. But you get the idea.
