(#0129) How to bring LCD Ghost Segments back from the Dead

Cleaning LCD Contacts on a Fluke 85 DMM.

Thanks to your video, I was able to repair my Fluke 85. Display is better now than it was 20 years ago.

Use your experience to repair an expensive digital caliper. Turns out the seal around the case had been misplaced in the plastic die cast seat. After dusting off and a clean install, display is back to life! THank you for the tip!

Just followed your video and was just about to dispose of my FLUKE 73 III

It worked brilliantly so thank you for taking the time to help others.

I now have a brand new meter ;)

Thanks for the info. I have a Fluke 87 that has been tucked away for about 8 years because of the ghost numbers on the LCD. I always figured it needed a new LCD so I used another meter. Came across your video, gave it a try and brought the LCD back to life. Now I can use the Fluke 87 again. Easy to do and a cheep fix for an expensive meter.

Surprisingly easy fix, in fact for me just opening the case and fastening the screws was enough! Who knew. This saved my small kitchen clock and made my day (surprising how hard it is to find a small unobtrusive battery powered radio controlled clock that reliably shows the time and nothing else). Thank you so much!

Thank you! This helped save my Oxo kitchen scale by visualizing the issue. The LCD was display just like the in the video. The design was different, this used a ribbon cable (not the clip in kind). I squeezed it into the circuit board and the display worked great. To fix the issue, I placed a thin piece of plastic so that it would increase the pressure by a little bit, enough that the display is now perfect.

Thank you so much Eric! I managed to fix my watch's LCD that somehow popped out of its plastic latch. As its was my first watch from many years ago, it means a lot to have it up and running again.

Just to thank you for posting this repair video. My Fluke 77 had the same issues, and I cleaned the LCD circuit board contacts as you've indicated. Presto! This cleared the issues up completely! Thanks!

It worked - Thanks! I looked at three different videos and each showed a different method (alcohol, silver conductive grease & buying aftermarket connectors) - might as well start with the easiest and see what happens. Glad to have the display back on my 27 year old Fluke 87.

My fluke 87 was saved by this video. Thank you uploader, for sharing this video.

My contacts were slightly different than yours but I followed your logic and actually fixed 95% of my screen! Thank you so much.

[jeffchen]

Thanks for putting this up ! I have a fluke 88 that was doing the exact same thing and the cleaning of the contacts fixed it.

Thank you for this video, I was able to fix my 9-year old digital scale. Followed your instructions to wipe the connectors with alcohol and now the lcd display is as good as new.

Fixed my old 7-segment clock thanks to this, much obliged good sir!

[rcari]

Thank you so much, I had that problem for a few months now and lately I was getting frustrated with it that I thought of throwing it in the garbage and buy another one even though they are pricey, thank you again so much😀😀👍👍👍

Those Zebra strips have always been a problem. What you did was the proper way to correct the problem. Some people will even go a little too far and take the Zebra strips off the LCD display which is a big mistake. Oils from handling Zebra strips can cause all kinds of problems. I used to replace them on all kinds of test equipment and learned the hard way.

Thanks. Your video helped me bring back my FLUKE87 display. Thanks again!!!

[rodneyjackson]

I am so happy, You have taught me how to fix or repaired my Fluke 87 multimeter, I am so please. My digital display is showing, just like new. You is a great teacher. Thank you very much.

I use one of those pencil eraser to clean the contacts first and then I use acetone to clean them. I also clean the ends of the contact strip with acetone and air blast everything clean and dry. Fixes it right up.

[garyjeffersii]

Thanks much for this. I ended up lightly scraping the contacts with a precision flathead screwdriver and all segments came back.
