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.
Have you ever done a conversion for an 8010a? Do you have any suggestions or ideas?
Thanks
Never had to fix an 8010A display. It only needs a very generic 3-1/2 digit LCD like the one I used for an 8020A replacement, so if the mechanical mounting issues can be worked out, that might be a possibility.
My Fluke 8050A meter head (LCD) is not showing any digits and I believe the meter is perfectly functional. If I can convert the display to LED, it will be great. Is any circuitry involved and if so can you send me that circuitry so that I can do some conversion of my meter to LED display.
Thanks and regards

In addition to the series resistors for each LED segment, there is a small circuit to deal with the minus sign and to drive the ‘one’ leading digit without overloading the driver IC. All of that is shown in the diagram included in the gallery.
