Hi... I own a old digital counter and the display is burnt. Do I need to know what angle is the old polarized screen or it doesn't matter? many thanx Marco
Can we not replace with the new LCD screen? After removing the old silvery screen, the numbers can be seen on the calculator without replacing with a new silvery screen, so not sure what’s the silvery screen for?
The silvery screen is aluminium foil with highly polished surface. Recently I came across another repair video where experimenter have used photocopy & glossy photographic paper as well that works fine. I hv ti try it out.
Sir "Dicky Junaidy"first thing thank you for comment me. Sir,when LCD back sticky plastic glue damage then its transparency absoutley gone thus the screen did no visible. In my sounding I found that the mobile inner plastic reflect light Like a mirror so in my opinion it would be ideal for faded LCD screen ,Or any short of reflective materials like aluminum foil transperen rapper plastic etc. Thank you sir & have a nice day.
Nice video sir! Do you have a repair method for when the clear flat flex with the black conductive traces has separated from the LCD? Do you know which glue I would require?
"Wasim Khan" first thing thank you for comment me. The name of liquid is thinner ,,,It help to remove the sticky plastic from glass ,,,It evaporate very soon no worry about oily ness in the screen. When you work LCD like this be gentle and do slow . Thank you for comment me & Have a nice day.

Nice video and I am going to repair one of my Casio calculator which has got the same problem. The problem is I don't konw from where to bring that aluminium foil and how to stick that on the LCD. This video did not explain that. Can someone help please?
Hi Nihar, very useful helpful educational video, well done. i I have a problem whith Instrument LCD Display of my car, at winder it is ok but at summer (50+ °C inside car) is faded, can I replace only the back with a aluminium adhesive tape ,I appreciate the time you have to take to help me, thank you in advance
This is a very great video, Great job. just moments ago i found the perfect LCD Plastic from a phone to work for me and it made the screen look and operate as the original did, but just after I closed it up before screwing it up, I tried it again and the words and figures would not show fully. I opened it and cut a new piece of plastic for it but it showed small pieces of everything. Can I get some help as to why this happened?
Your flat flex cable will not be making perfect contact. I don’t know yet how to fix this aside from using something to apply pressure to the plastic flex cable.
@@Infiniti25 I gave up on it and packed it in a box, then for some strange reason my mind told me check it out again and when i did, it was working perfect. to this day i'm still using it. Just when i was about to order a new one.
My brother " thenet " thank you for comment me. When i saw my calculator a black shadow appears then I think how to remove ,,,you are wright that do not use razor blade but the Casio tightly paste with aluminium back as you saw on my video,,,, so I think thinnest type element to remove this thing so I decide to use razor blade.my brother thinner is a substance which used to dilute paints it easy to remove the sticky paper . Thank you my brother & have a nice day.
It is a very common problem with this kinds off calculators, simply you just open your calculator and open display and rubber connectors ,wash it with kerosene and put these two component in full sunlight for hole day , then fit again ,after that your calculator screen work again like new one
My brother "Kotn" first thing thank you for comment me. A paint thinner is a solvent is used to remove the sticky LCD Back sticker ,,,,, Thank you my brother & have a nice day.
Bro mera calculator ko aisa black me nai aare phir bheech me numbers aara nai And can I use computer cleaning or nail polish remover instead of solution in injection
My brother " punnana Laxman " first thing thank you for comment me. Use these , kerosine ,paint thinner ,petrol Be stady and calm use not to use sharp blade try to remove plastic not scratch the back side of the LCD. Thank you my brother & have a nice day
My sister "Aishwarya Biradar "First thing thank you for comment me.If the letter's are getting invisible day by day you need to remove the back side sticky reflecting plastic like me ,,,without damaging its contact wires go steady and slow. Thank you & have a nice day.
My brother the reason is that the back sticky plastic glue removed when it becomes older so you can use aluminium glue tape for better view ,,, also you can try UV but I did know how it works. Please comment me if it is work. Thank you & have a nice day.
My brother first thing thank you for comment me . My brother there are many reasons for diming screen. Problem in carbon strip Moisture In board Low battery Screen sticky plastic damage First check battery then comment me. My brother thank you & Have a nice day
My brother " Edy Lay " thank you again comment me. My brother just follow the procedure if your reflective paper is damage then carefully remove the sticky reflective plastic then clean with paint thinner or petrol is used to remove the sticky surface ,,,cut a piece of aluminium foil stick it back applying hot glue back side corners to stick reflective foil close with your screen .If the black black liquid crystal is entire screen then it will not repair.If your screen is like my screen it is repairable.
My brother "Edy Lau " Nail polish that I did not use because when it dry it can be easily out the surface looks hollow or rough ,,,,, So my brother go get catbury chocolate aluminium wraper or some short of aluminium stickers used in bike asseries shop . Or oil print aluminium colour paper is also used as a reflector.
My multi meter not showing display. I. C. is good but surrounding pins of I.C.somewhat blackish due to once it was small short circuit all the parts are very good as well main I. C. ,Also buzzer is also not working. Pl give the solution sothat my millimeter can be repaired.

Si pongo la pantalla de una calculadora a otra de otra marca funciona
it is better using a polarizer film sprayed with silver paint for LCD back reflective replacement
Kalo pake hot blower mungkin bisa membantu supaya lem lebih lunak... dan mudaj di belah
