- My multimeter lcd have annoying big black spot on it. That made me hard to read number, so I decided to fix it without paying money because the multimeter cost not high.
This method not cost you at all because the material I used was in my bin.
Thank you for the video. Excellent idea. I have repaired the LCD display of my laser distance meter (DLE 40 Bosch make). For more brighter display I have used aluminum foil as back reflector instead of white paper. I have used iso propyl alcohol for removing the glue layer. I have always thought that the problem is within the LCD plates and so not repairable. Your video has shown that the back reflecting layer is the one that get degraded. The aluminum coating in that layer is actually getting oxidized and losing the reflecting property and forming a dark patch. Thank you again.
You're welcome and thank you for sharing your experience.
Thanks a lot for ur positive response.
I hv seen many such video but u hv explained the background theory of this problem, this helped me hain some coincidence! I will soon try on one of my three meters. 🙏🙏
Excellent, thank you very much. I did it on a guitar tuner and now its useful life has been extended.
Great!!!😀😀
Thank You Sir, By the guidance through this video, I successfully
repaired the display of my digital diary CASIO SF-3990. Am really very
thankful of you to share this kind of precious knowledge with all of
us.
+Amit sharma You're welcome. Thank you for the compliment.

You're welcome.
Very very helpful video thanks a lot. I fix my multimeter and AC remote after watching this video. Thanks.
You're welome.
Excellent, thank you very much. I restored my Casio MJ-120T calculator, which I almost threw away due to the display issue!
Congrat!!!
Great tips, thank you for sharing, saved mine. Though I lost a good excuse to my wifey for a new one to buy :))
You're welcome and thank you for a positive comment!!!
But u saved that the money & what about that happy face of lady of the house.😊.
Wow! short but informative video. this one made my multimeter better. you earned another subscriber. thank you.
You're welcome.
Hello I have an LCD and the screen just froze. Even with no power i can still see all the digits. I tried to change the polarised film and used paper as a background but i can still see the digits but no so intensely

Hope the contacts r clean!
By the way what was the status of the LCD screen when it was lifted-of the board?
Pl do share 🙏.
Your post is very helpful and I also followed that. Thanks for your post.
You're welcome 😉
is this works on BP monitoring machines display also? and what kind of paper is that white one you stick on the screen?
Yes. I use glossy white paper.
My Casio calculator (fx-82ms) has a big black spot on it. However, the LCD is connected using a flat, zebra-stripe LCD connector. Now I am scared to do this myself because I don't know how to remove or connect a zebra-stripe connection. Any answer? Thanks.
Remember the zebra-stripe position and everything will be fine.
Have you done fixing your casio fx82ms? How was it? I got the same problem. 😭
I'm replying because I have the same problem huhuhu I want to do it but I'm scared coz I dont know how huhu
You can do it, keep a zebra-stripe from dust,oil.
Good instructive video! I'm going to try it out on my remote control that has an LCD screen that is turning dark from the middle. Thanks!
You're welcome. I'm sure it will be good again.
Hi what type of paper do you use?
Any help will be apreciate.
Thanks so Much.
Ricardo B Just normal a4 paper is enough, but glossy print paper would be better.
Your method is wonderful, short-cut and effective.
I have repaired my costly hioki clamp meter 3280(Japan)
which get black spot on display.
Thanks.
You're welcome and thank you for sharing the result here.
Thanks for your video. Does it work also for a Casio My Magic Diary? I think it has the same problem.
Yes, it does.😊
Thanks a lot. I just saved myself from buying a new multimeter.
You're welcome!!!
0:50 Those pink rubbery things that hold up the LCD, do I just glue them back on? I peeled them off but I am not sure how to get them on.
Yes, just attach it to the lcd display. It's will be stick to the lcd when you put the circuit on it.
Saved mine as well. Thanks for sharing
You're welcome!!!😀
Muito bom amigo !! Qual tipo de papel foi usado ? Se usar papel alumínio com fita dupla face resolve ? Muito obrigado por ensinar. Eu vou tentar no display da minha bateria eletrônica Alesis SR16.
English please.
I dissembled mine buy I am getting an issue when i reassemble, it no longer works, when pressure is applied all of the items on the screen light up, while fixing the spots one of the pink rubber ends have moved out of place, how do i fix this?
You need to use something the a littele heavy press on the screen, where the rubber attach to it. You need around fews hours to make the rubber stick to the lcd display.
@@Easyandworksproject all of the digits and icons on the screen light up when pressed down
You need to press over the lcd screen where the rubber attach to screen for fews hour with something a little bit heavy.
@@Easyandworksproject when i do that all numbers are showing at the same time brother, no readings can be made :-(
@@wizardman1313 yes, when you press lcd, all digit will show but when the rubber stick to lcd and you move the heavy object from the lcd. It's willbe fine again.
Thank you very much for this wonderful video
+shagar cool You're welcome🙂
Which Multi-purpose cleaning compound to use? Can I use isopropyl alcohol?
I'm not sure but I think it's ok.
I've used almost chemical compound/liquid - kerosone, gasoline, crude oil, Olive oil, Isopropyl Alcohol, Lighter Fluid, Penetrating oil. All are SAFE to be used but none of them gives easy result in removing the residue. It's a matter PATIENCE.
@@jogicaballes8730 Eucalyptus oil (Australia) removes glue residue instantly, and doesn't damage plastics. It's amazing.
@@wizrom3046 Thank you mate. I'll try to see if this Eucalyptus Oil is available in Philippines. Stay Safe
Sir my watch is got burned like that. Not the polarized but the main the digital. Is same problem? I just using a paper to fix it?
You need to try and see if it works.😊
Just using a white paper? Can i use white stickers or something white like paper?
Yes, you can😊
Creative video, thanks :)
tnx because it works on me...many thanks
+Kevin dazo
Sorry to reply late. I'm glad it works for you.
Thank you and nice video to share!
You're welcome
can we fix a broken glass of a lcd display
+Chamindu Sandaruwan LCD display has transparent conductive wires print,so you can't fix it🙁
Will this work for a nintendo game and watch
This method works great for monochrome LCD.
That paper name what, were get that paper
The paper is a sticker paper (the side that doesn't have glue) you also can use glossy print paper(use glossy side for more contrast).
well done
+Ricardo B Thanks!!!
You are have this skema multimeter
??
Which paper to use
Normal white paper.
Just now I've repaired my MECO 9A-06 digital multimeter by watching this video!! First of all I've not dared to repair black spots and was thinking for a week, because if it gets repaired then it's ok but suppose the display fails then I'll have to throw my Meco DMM.
But at last it's done by peeling reflective screen on the back of the LCD, I've not scratched it's back, and replaced reflective screen with a photo paper which more shiny than normal A4 paper.Thanks for the useful video.
Great, thank you for sharing the result.
so the back of lcd can replace with A4 paper?
Yes, but glossy paper is better.
@@Easyandworksproject Ok thank you...
I thought I'd give this a go but gave up in the end. The reason why, the silver backing on the LCD was practically like a thin film of paint, even though it was obviously a self adhesive backing layer that had been stuck on. It would have been too problematic, messy and time consuming to try to remove. I stopped after just removing a tiny bit of the corner of the backing and reassembled and luckily it was still working as before with the faulty screen. I guess they manufactured multimeters LCDs differently at some point, as mine did not just peel off like the one in the video.
Thank you for sharing your experience.
I repaired my weighing scale's lcd screen using this. It improves alot but a black spot is still visible. I probably left it there for too long. Thanks a lot!
+Bob Yong You're welcome 😉
Thank you for sharing the result.
Thankyou dear brother you helped me bring my lovely multimeter back to its life.
My pleasure. 😄😄😄
could i do this on my fieldpiece HG3 it has a few black spot and it is faded a little bit ?
This method works with any monochrome lcd
Thank you sir for this tutorial. I was able to fix the Black spots of my SANWA Digital Multimeter. Though it took me almost an hour to clean the sticky residue.
+Jogi George Caballes You're welcome and thank you for sharing the result.
Hi sir, what kind of paper do you stick back to the lcd?
A4 white paper.
Nice video. Would this method work on a display of casio wrist watch?
Yes, if it has the same type of LCD display.
What kind of paper is needed
You can use any paper sheet such as A4 paper but glossy paper give better result😊
Good. So helpful post.
Thanks!!!
Hi, great tutorial! But when i peel off the sticker some of the black thin film is peeled as well. Can i just remove it completely and change with new lcd polarizer film? Thx in advance!
+flaz82 Sorry, I 'm not sure about it.
Would you please guide me about which layer to peel. The polarizer film or the non transparant one?
+Edward Ong You must remove the polarizer on the bottom only or the LCD cannot works.
