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
Hey Nihar! I had exactly the same problem in the same calc :D. Could repair it 100%. I replaced my back with a fluorescent paper as I didn't have any aluminium. Looks great now. Thanks for the guidance :)
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?
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... 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
Keeping this same model scientific calculator unused for long time, the screen is blackened. Should I use this technique on my own or get it repaired at some repair shop? Is it safe to do my own. And why you use paint thinner and from where can one get mobile paper that you used?
" Ajeet Kumar " sir thank you for comment me. Sir the screen darkness is basically two type 1-Liquid Crystal blackness. 2-Reflective plastic darkness. Liquid Crystal blackness is not cureable ,,some people heat the screen using flame it is totally wrong . Look deep inside the reflective plastic damage is oval,rectangle ,round ,shape,triangle blackness will apear it means you're reflective plastic glue damage. I use blade because the company fit aluminium plate along with the screen . You can use any reflective paper like biscuit plastic back side. You can also use petrol as solvent which easy the plastic remove. Use nail with soft touch when removing the back plastic. Thank you " Sir " & have a nice day.
Sir, I have one of like this complaint with the display is fading by adding three or more digit. When I replaced the battery also. The problem is still there, how can I solve this problem.
My brother "Hadi Suprapto" its my pleasure to serve the video. I am happy that I have got a new brother from Indonesia. Many many loves from India India and Indonesia are two brother Like both nations starts from letter "I" Thanks my brother have a nice and great day Namaste "Jakarta".
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.
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.
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.
