Not sure exactly, but component level considerations would be the varistor, and/or aged capacitors.

@@MultimeterParts id imagine old age as well. But once the voltage is applied it's absolutely spot on. I enjoy this channel very much! (Technician on Italian machines for CGM) I use this 20 year old meter on a brand new TC2-H1700+P

The differences between the Fluke 87 and Fluke 87 III are: Fluke 87 III has the newer white LCD backlight, as well as an easily accessible 9v Battery via the battery door. There are subtle upgrades in the specs with the Fluke 87 III. The legacy Fluke 87 and Fluke 87 III are still solid industrial multimeters. We hope you get get another 20 years out of them. Thank you for your comment!

Excellent! Happy to help!

at beginning of video 'Auto Range' (lower left of display) is only thing I could see that might be faded

Try disassembling completely, and spraying down the main PCB (circuit board) with 90% (or higher) Isopropyl alcohol. Let it air dry for a few days, then re-assemble and see how it goes. Please share updates. Thanks for commenting, and good luck.

@@MultimeterParts There is something burnt around the zinc covering the PCB, could that be the cause?🙏

@@Dendyfeb yes, but clean with the 90% or higher alcohol. Make sure it's not surface rust. If it's obvious that it's burnt, then need to replace that component, if possible. Less replaceable parts on Fluke 87V, so may need to replace entire PCB. If it's only surface rust, then there is a chance it can be cleaned and brought back. Good luck! Thank you for your update!

Are you looking for a Fluke 87 LCD, or Fluke 87 V LCD? We may have both in stock. Will get back to you. Thanks

See other videos on this channel. The basics are the same for all models in the same series. Example: All 80 Series Include all Flukes 83, 85, 87, and 88. All 70 Series Include 73, 75, 77, 78, 79, and all 170 Series include Fluke 175, 177, and 179.

standby, will add link. thank you.

link to Fluke 23 disassembly and LCD removal. Use this for Fluke 78, all other Fluke 70 Series, Fluke 20 Series, and Fluke 50 Series Thermometers. They are all the same. Use alcohol pads to wipe the top and bottom edges of the elastomeric connectors, and then simply re-insert.: ruclips.net/video/fSe6gYGePiI/видео.html

can use use isopropyl alcohol 70%-90%

all elastomer display repair kits $14.99

Awesome! thanks for sharing.

Will look into posting up on this soon. Thanks!

I found them for sale on fleabay for under 20, and it has worked no issues

@@spartanreece9908 Maybe I'm blind or have zero idea how to use the old fleabay any longer, but there are no 'screen' or 'kits' or pretty much anything for the Fluke 87. I guess I continue to take it apart, clean the pads, and move on. Probably the last Fluke I ever buy after their piss-poor customer service with me (and yes, since I bought the meter).

We'll update this information based on your recommendation. Thank you. Try cleaning the display contacts first. If display is only fading, then cleaning will fix it most of the time. Thank you for your feedback, and check out our multimeter parts site...we're updating our database. Thanks again!

We apologize for the late reply. When the LCD is bleeding, as in the case of the black spots, then the only solution is replacing the LCD. We do not have this in stock at the moment, but we are updating our inventory and website. Let us know what you're looking for and we'll do our best to accommodate. Thanks for checking us out.

We're updated our Warranty to 12 months...1 Year. We're updating our database and inventory of replacement parts. Thanks for your feedback.

@@MultimeterParts Ordered new gray elastomers for my very old Fluke 87 and they work great. Thanks

Terrific! Thank you for your feedback, and we're always here when you need us. Cheers!@@9ballz

Terrific! We're glad it worked out. Thanks for your feedback.

This is great! We're here to help, and glad it worked out.

Si la pantalla se desvanece, intente limpiar antes de reemplazar los conectores elastoméricos. Si es posible, ¿puede incluir una imagen de su medidor? Veremos si podemos diagnosticar. Gracias por tus comentarios. If the display is fading, try cleaning before replacing the elastomeric connectors. If possible, can you include a picture of your meter? We'll see if we can diagnose. Thanks for your feedback.

Esto puede ser una falla de un componente interno. Reemplazar la batería con una que se sepa que está en buen estado no solucionará el problema, si este es el caso. Para diagnosticar, será necesario abrir e inspeccionar la PCB principal. Puede deberse a una prueba de sobrevoltaje en el medidor. Espero que esto ayude y gracias por tus comentarios. This may be an internal component failure. Replacing the battery with a known good battery will not fix, if this is the case. To diagnose, it will require opening up and inspecting the main PCB. It may be caused by testing over voltage on the meter. Hope this helps, and thanks for your feedback.

These gray Fluke 170 Series elastomeric connectors may be found on our website here: multimeterparts.com/replacement-parts/fluke-170-series-elastomeric-connectors-j1-j2-650264-replacement/ Thank you, and we look forward to accommodating your parts requests.

Thank you for your feedback! We're glad it worked out.

Awesome! Thanks for sharing!

Six years and counting...and here's to many years to come. Thanks for sharing!

Let me see what I can find out and will get back to you. Thank you for checking us out!

When you state it's the same way, you mean the display is on VDC, for example, for all the functions? Is it all zeros? Try taking apart and making sure that the range selection knob is positioned correctly and that all the contacts are clean and in the proper place. I'll try to post a video of the Fluke 77IV, or compatible soon...if I have one. Thanks for reaching out. I hope this helps.
