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!
I fixed the broken LCD display on my alarm clock by heating it with a hair dryer and then giving it few taps with my knuckles. Completely restored now.
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.
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.
So much for Fluke's reliability and durability of their overpriced products. BTW, that solution will only work for a while and then the problem might come back again, much like some TV remote control buttons.
@@ElectronicTonic156 Good to know, thanks for the follow-up. But many times those elastomer strips fail at some point because of poor contact with the PCB due to shrinkage or hardening after many years. Some of them might also lose some of their conductive properties over time, too. I'm a little surprised that just one cleaning with alcohol six years ago managed to fix it permanently.
I know a little of English language, because in my work I have to Know English and French Languages, but I understand your problem, cause I also have sometimes problems with technical words! Then I used to go to the "configurations": in the "right corner of the video Image", click on the "wheel" and after the opening of the "new image", select "legends", click on it and there you have a new "image" with: all the word translation languages, where you can choose your preferred language. I hope have helped you a little, Marcio Amorim Rego ! An embrace from: carlitos
I find with the zebra strips on LCD displays and carbon contacts in remote controls it's always better to use methyl hydrate then rubbing alcohol though it did work well for you and that's great. Also you might try 99% instead of 70% alcohol. Looks good though.
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.
WOW My fluke 83 has been doing that for about 4 years and its 25 years old. So I asked a question why does it have this problem. In the time it took to watch this video I had it fixed. I can't thank you enough thank you thank you thank you!
A wary old and effective trick that are being used in the PC repair industri is to use the brown and blue ballpen eraser and some 90-95% Isopropyl-alcohol.
I'm curious how the rubber strip comes into play to push allow display on lcd? Is there light shining through the rubber strip? Does the rubber strip have to be perfectly aligned with slots/holes on the strip? etc
There is no light. It is about electrical contact. The rubber is basically a conductor (the black stripes are conductive). The same could be achieved with a ribbon cable or a bunch of individual wires. Each segment of the display requires one wire, plus one more wire for the common ground (or rather common plus contact).
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.
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 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.
Works like a charm. ALSO I'm sorry you broke off one of your little retaining clips (in your video) But that too was instructive and cautioned me to be watchful because I may have done the same thing as well as being mindful to orient the mode selecting rotary switch during reassembly, So let that be a lesson to would be posters in a "how to video" that your "mistakes can be equally informative and should not be "edited" out Great job and thanks for saving me money and frustration TIM
Totally agree! It's probably not too uncommon for people who are making videos like this to edit out all the little mistakes, simply because they have too much pride to include the mistakes in their videos. But just as we can learn from our own mistakes, we can also learn from other people's mistakes as long as they are being presented to us.
+Eric Wasatonic hioki multimeter are so much mìbetter !!! fluke bullshit ,also for the price check out hioki and you will understood about what im talking ;)
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 ;)
thx to your experience and a few other youtube videos covering "Zebra" rubbery conductive contact strips that are used to connect circuit board contacts to LCD contacts and how to clean them - i was successfully able to restore my LCD display functioning on a very expensive race car digital dash display - cost $0 - just 10 minutes of my time and some research and patience
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.
Very cool ! I'm trying to fix the LCD on my car radio. I don't see a rubber connector piece though, like here and on other videos. It instead seems to have a tiny row of female/male connector pins . I'm not sure if that's the right term - I'm just starting to learn more about electronics...
just done my Fluke 73 - this must be one of the easiest wins in electronics. I had put if off for too long and it only takes 5 minutes. NB pcb screw under fat HRC fuse.
Hi, my calculaor watch isnt working! ive just desambled the watch! Seems like there is some zebra strip missing that connects the mainboard right? Ive marked it for you with a question mark where i think the zebra strip is missing in my opinion. drive.google.com/file/d/1Rk-ks46crh6vXIKXlHnnitb3zJpQVLKp/view?usp=sharing can this stripes that connects the board, bought afterwards?
Great video. I looked into repairing an old 15 kb digital diary. Not so lucky with mine, my ribbon traces were basically petrified when I opened the case and one little touch knocked the whole ribbon connection off the board :(
Did Fluke have a lifetime warranty on their meters a while back when they were more premium? Is that no longer offered because the construction quality has been revised for affordability?
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.
I also use contact cleaner on the pink contact pad that makes contact with the circuit board. It's very amazing how sensitive those LCD's are to a minute amount of voltage drop.
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.
Nice. You got lucky. The process of cleaning the zebra's and solder pad surfaces is always a crapshoot. Sometimes it works, sometimes it doesn't. So, you won this time. The amount of pressure against the strip is CRITICAL. Can't be too much, can't be too little. Sometimes the strips deform slightly or "shrink" slightly over the years, which can be enough to cause them to loose good contact. Even a few thousandths of an inch of dimensional change is enough for them to not work. So the shimming approach does sometimes work (but use only a TINY amount of shimming. If there is too much, the strip will get "squeezed" too much when reassembly, causing deformation, and the same poor contact problem). By the way, although Fluke no longer sells replacement strips (the woman in Service Parts actually laughed at me when I called--"Sir, your meter is 28 years old, we don't have parts for it anymore"), the strips for SOME models of Fluke DMM's are available from one or two places on the Net if you search hard enough. I bought a few for my 87's a few years back. Heartbreaking to consider trashing a $400 (more now) meter because of 20 bucks worth of silicone. Best wishes.
Thanx, i need to try this on my Beckman 3020 as it has the same problem, and i "fixed" it the same way (putting more pressure onto the LCD) but the LCD went dark at some places, so i´ll give your kind of fix a go, as it won´t get whorse...;)
Just replaced the "elastomeric strips" in my Fluke 77 after 30 years due to missing character segments in the display but that wasn't the fix. One of the PCB solder connections to the elastomer strips had rotten lead which didn't respond to contact cleaner. Scraped it with an Exacto knife then more cleaner. Works good now. Save your money and remove the 4 screws holding the LCD tower ass'y so you can examine the PCB contacts and clean them. If that doesn't help then try new strips.
Unfortunately this cleaning process works only temporarily. Soon the same problem appears again and again. One needs to replace the elastomer contacts stripes with new ones for long term cure of this problem. I had the same problem with my own 87 (first generation) which revealed this problem so many times in the past and was really annoying if not completely frustrating, given that I spent a lot of money when I bought it. I paid a one month's salary to buy it back in 1988. Excluding this problem, which appeared relatively very soon and it's a shame for an instrument like that, I had no other problems until now. It remains the industry standard instrument.
Hey, idk if you can help me, but instead of having dead "pixels" my alarm clock has "broken numbers". So e.g. the right bottom piece of the 9 is missing, but when it shows a 7 its there. Must be a chip that went bad, right?

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😀😀👍👍👍
Cleaning with alcohol does work, but it's not a permanent cure. The problem will reoccur. I have to clean mine once every three years. Also, clean the strips as well as the contacts on the board, the alcohol will not harm the strips.
alcohol.... the solution to all of life's problems
Hobbyists can get 99% Alcohol from Amazon. Pure acetone can be used to clean connections or left over flux.
Hahaha !

I have the same issue with a cb radio but the practical application is exactly the same. Thanks for sharing this video. Kind regards. Paul.
My contacts were slightly different than yours but I followed your logic and actually fixed 95% of my screen! Thank you so much.
Instead of alcohol, I'd use "tuner cleaner" to remove and neutralize any oxidation on the contacts.
Nice repair. How long did you wait for the alcohol to evaporate?
Thanks. It was only a few seconds to evaporate.
when the screen went bad as you accidentally lifted the other connectors also showed a place to look for corrosion.

I was sure that Fluke USA ad a lifetime warranty on their USA build voltmeter...???
Awesome video, worked perfectly. 8sed a hair dryer instead of toaster and the screen is perfect again
tough luck; most of the times the board is warped on an arc and the strip makes bad contact; so you need drastic measures
had one of these fluke 85 with a issue with screen for over 30 year and 5 min after watching your video its fix thank you
