Fluke 77 LCD?
« on: October 08, 2019, 04:53:06 pm »
So....I was given a Fluke 77 with intermittent segments, easy enough to fix. I've done many and similar.
The problem is someone was in there first and messed up the plastic retainer. When I was putting the clean zebra strips and LCD back together, I didn't notice that part of the retainer had a bit of plastic that was damaged and sticking out, and CRACK! :palm:

Checking for both part numbers, I found no replacements, other than ePay at an unreasonable price to justify repair. Anyone have an idea where to find one?
Or, should I call it :horse:

When you said Fluke 77 you say the old model right, the one that looks like a slab?



The design is the same as the 73, 75, 70, 23 and 21 from the same era right?

From where I looked, I wasn't able to even find some as eWaste that I could use the outside. Even talked today with some people I know in the electronics market and nothing.

Your best chance is try to look for old stock from a repair shop who turned belly up, or buying another one just for parts.

Well I appreciate you trying to find one at least.

Like I said, there are people who gouge the market. It's because they think they have a pot of gold, until one day a new meter is $10 and can do more. Their parts or product will be become useless sitting on a shelf or discarded never helping anyone because of greed. It's about making way more than enough money and not helping repair something. eBay is full of them. The buyer will set the market not the seller for people like this.

It's such a shame Fluke made this and knew that the zebra strips were failing in subsequent models. Their response, keep making more the same way and don't fix the mistakes. Just tell the customer "buy another one". :-- Shame.

Exactly my point! No the meter is not worth it. It's just sad that it will be put in a box of crap somewhere to be discarded.

It's a bit expensive but it's a decent meter so maybe worth the $$$'s ? ?

Yes, it's a shame for sure! A nice old meter going to waste in a drawer or whatever because the part to fix it is worth more than the meter is now. I would be tempted fix it myself but that is just me  :scared:

Maybe sometime soon someone will see your post and either have a broken meter themselves or know where to get the part you need.

Well sadly I'm in China, if I was in Portugal as a fellow Portuguese I would buy you that DMM, repair myself even costing a lot more that the price of the equipment, and keep it for using it. I hate so see a good equipment being put on a shelf without use. I have the same problem with my Fluke 54II Thermometer. It have the back and front cover cracking in lots of places, and it's been a pain in the rear to find someone selling parts for it. Fluke Portugal that it's represented by AresAgante - https://www.aresagante.pt asks me for more that 300 euros just for the back assembly that includes the back plastic, the battery contacts, the shielding and one more part. That just the back.

That equipment suffered from Alkaline battery leakage, that even affected part of the PCB, having 2 or 3 contacts on the IC with white stuff. I cleaned with 99% Isopropyl Alcohol and a toothbrush and it's now like new.

But the back inside is all corroded, the plastics cracked near the screws and on the top were the connections to the thermocouples are located. So a overall outside cover refurbished is needed. By the prices of it it's easy to buy one new here in China, being the 54IIB that to repair my old one.

Although I still didn't drop the towel, some day I will find at least the back and front shells and import the rest of the stuff that I still have and will have a fully functional equipment.

Cool site! There should be more of them for all the older meters and stuff selling the parts at reasonable prices. The site I listed seems to sell mostly parts for newer meters.  :(

This guy replaced the LCD display on his ham radio with a "generic" one.
http://www.retro.co.za/zs1ke/FT-290R/reverse-engineer.html

i can see two problems in your case, --- not enough room to fit an auxiliary driver board (although he had a similar problem, as the FT290R is very small)

& "the biggie":-

You lose any special characters.

This wasn't so important with the radio, but may be a "deal breaker" with the Fluke!

My question is really there is any advantage of the price of the screen itself is that much that does render the repair of the equipment itself?

US$41 is around €35. If the seller sends in a small bubble envelope with cardboard on top and bottom it will go through customs without no one stopping it (normally small boxes are stopped, envelopes that small no. Everything from China that have a Small 1000x100x10mm box and above stops without fault, regarding Portuguese Customs. It doesn't matter if it's marked as Gift, or values below €10. It will stop and be open. If they are in a good day it may pass but when it was with me I never had that luck).

Doesn't it render the repair of a equipment that may value into near €100 to a collector if the condition is great? That is my question?

What? Can you rephrase this in a comprehensible way?

We should hope they don't pack it like that, since packing it with nothing but cardboard for stiffness is a way to guarantee the LCD gets cracked in shipment!

You mean, is it worth spending $40 to repair something that might be worth €100 afterwards? Maybe. Depends on how good a condition it's in otherwise.

Sorry, I didn't read before.

What I wanted to say was if the price of the screen itself, being kinda low (not 100s) doesn't render the repair of the equipment a viable option?

If it's thick corrugated board, and inside is used packing bubbles, only if the mail man is a beast it will arrive damaged. Some years ago I bought some American Comics Bagged and Boarded, and they came in a packing envelope with 2 thick corrugated cardboard sheets without any damage and creases.

This one already is the same as the first quote, again my mistake in writing while in a hurry.

:palm: A comic book is made of paper, so it can handle substantial flexing before damage or creasing occurs. A bare LCD is a sheet of glass. It can handle no flexing. I am incredulous at the need to explain this basic knowledge. I'm similarly incredulous at you believing that the postal services will handle everything with kid gloves. Have you SEEN the equipment used for automatic envelope sorting? Have you SEEN how everything (be it an envelope or box) begins its journey by being unceremoniously dumped into a bin or bag? There is nothing delicate about any part of the process. It's miraculous that anything arrives undamaged!

Ladies and gentlemen, here's a living specimen of why vintage equipment routinely gets smashed to smithereens in shipment: the assumption that the postal service (or courier) will not be "a beast", and think some bubble wrap, packing peanuts or crumpled newspaper in a cardboard box is enough.   |O


P.S. Please use the quote tags carefully. In your last reply, you completely mangled who said what.

OK, post before re-edit to add the lack of quote lines to separate replies to replies, again my mistake and I'm sorry for my lack of English, It's not  my mother language and even now I still make mistakes.

Second, sorry for the lack of insight regarding the assumption that postal mail services can treat a parcel properly. Yes an LCD doesn't have that flex because it's glass. My mistake again. The seller probably will send that in a small light box for sure, and will pack according not as I said above in my mental diarrhoea of reply specially with my example (really what were I doing or thinking to give a so stupid example).

So for all of that I'm sorry.

Between 2006 and 2008 I worked in the Portuguese national representative of Yamazaki Mazak CNC machines and between 2010 and 2015 on the at the time the biggest Telecommunications company in Portugal, TMN. Both times I was with the service support to clients and machines by association also RMA department of receiving and sending broken parts to Yamazaki and to NSN, and I was the one who unpack and pack everything and no parcel arrived damaged to the destination, via DHL or TNT or other transportation service. Between 2010 and 2012 I also worked in the Lisbon Airport in loading and unloading airplanes, at a 4.5hours part time to get extra money, so I saw how things are threaten and how they are loaded and thrown inside the lower cargo haul of an airplane by workers. I kept in the warehouse lots of packing material and extra boxes that I would just reuse when needed.

In all my sales on eBay no item I packed arrived damaged, and I sold from small very fragile items to heavy network switches and normally I use a lot bigger box that necessary and a lot more bubble wrap and packing material that necessary and a lot more tape than necessary, including reinforcing corners, sides, and protection against water with black wrapping film (3 to 4 turns on each side) since things go by airplane and when they are loaded on the airplane most of the times they lay on a cart, near the airplane while raining without any protection.

If the item is small and I have space on the box I even create a suspension system with elastics and cardboard, to suspend the item on the middle, with packing on the bottom, and packing on the top, so if any hit that may cause deformation on the sides or perforation or a very high drop or shock will not affect the item in question.

In some special cases where movement should not really be allowed and the price of the item itself is too high I use Instapak Quick Expandable Foam Bags and affix G sensors outside of the box, and all goes insurance to the price of the equipment sold, in all sales, with photos kept for reference how I sent that are sent to the buyer in question.





And when I say thick corrugated cardboard I'm talking this kind of sheets (I have some of this exact models, that I cut to size):





So with all this practice and how I've done things I still don't understand why I used the stupid example of the comics books, probably I wanted to use the simplest example of packing I remembered or probably as said before it was a mental diarrhoea (the second for sure).

So please save the emotes and your own assumptions of intelligence or ability of someone to yourself, as I do when I reply to others, even being the most stupid and logic answer I can give.
