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.

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.

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.
@douglas2lee929 Жыл бұрын
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.

@@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.

@dronillon257811 ай бұрын
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).
