I've a very old original (first version) Fluke 87 with the classic fading display due to the deteriorating elastomeric zebra strips.
I'd already tried most other fixes suggested bar a proper replacement strip.
Unfortunately the plastic display mount clips have also deteriorated so badly that I dare not risk breaking another one, as I'd already lost two of the four.
So, as a pure "Hail Mary", to see if it made any difference, the last time I was inside the case (which you had to do to change the battery in the first 87's) I decided to drop some Deoxit D100L under the strip, and give it a gentle massage. This was the pure liquid stuff that you apply with a brush, not the spray stuff.
24hrs later...
...well bugger me, the display is near perfect. 😃
And it still is, 6 months later, as you can see in the photos. 😲
I know a proper fix would be a new 3rd party strip but I can't do that without spending proper cash and hunting down a new display mount too, and it's just not viable or worth it for me.
I imagine there will be others in the same boat so I thought I'd share, just in case.
