3:03 It is not polarized film.It is a reflective film.Sorry for that

I'll bet you never realized how much this video helped, at least to one particular person who really loved his device.

Thanks for the video. I repaired my calculator according to the instructions and now it works perfectly.

I did it according to your instructions and it worked perfectly. Thank you so much. Very helpful and I am happy.

Awesome! Good job!! I don't have the guts to do it for my casio but this is a good guide :)

many models of other brands does not have a back metal plate. removing the silver film is as easy as picking the corners of the film and peeling it off. tweezers help. for those models there will be no need to use glue dissolving solvent. ive fixed 1 multimeter and 2 calculators to date. no issues. FYI i use white paper as replacement. works fine. hope anyone who reads this find it useful. have a nice day

Thank you so much!! I was suffering from this problem for long time! Thanks a lot!

Well done young man. A very helpful video which can be used for all similar LCD screen issue. God bless you and your family.

Awesome! Will try this with my old casio. Very nice "how to". 👍

Thank you so much. I have fixed my 570 ES. Lcd was completely unreadable. Now it looks great.

Lemme try to do myself,thanks for guidance ❤️👍

Great video. Tried this with my calculator but I must've broken the display. It still works but it can only display a few items. If I try to type in a large number, it gets dimmer and dimmer until I can't see it. This also means that I can't see pages like the setup or mode. Bummer Edit: Giving everything inside a good wipe with a dry tissue seems to have helped. The problem is still there, letters get a bit dim in the MODE page for example. But at least I can read them, and the calculator is usable now for my purposes.

Good job brother, Keep it up ❤️❤️❤️

Thank you so .much it was useful.

Thanks a lot bro for this video.❤️❤️❤️🙏

Had been facing the same problem alike, I was fixing it and used surgical spirit (80% Isopropyl alcohol) in excess. And for the reflective film used junk wrappers 😅. After I assemble it. Couldn't turn ON. Get disappointed and ordered new one that cost a thousand on Amazon online shopping. After a few hours, out of curiousity I was trying it for the last time and astonishingly it works. Could have been due to gradual drying of the wet LCD display.

I used white paper as a replacement of a polarizer worked great 👍

Excellent work!

Adoo, Gammk sago, wade goda❤

Great I have same issue... Now can fix it

This is awesome video!

Very very useful video

It clarified my Doubts

The "damaged" film you removed was not the polarizing film, its just the reflector, but your repair is effective nevertheless.

Keep it up brother ❤️💪

Thank you sooo much broooo😍😍it worked❤

Thank You for this Video

Great work Thanks

I have no word, to thank you

Obrigado pela dica.

Excellent guide.

Great!!! It work!! Thankyou!!

i just removed the reflective film and placed the metal piece. though the metal piece is itself colored in silver i guess no need to add anything. Its working fine. thank you.....

Great job brother

Bro .... now I can use my cassio fx 82 ms calculator again...❤

Bro..good work. Btw the damage film is not a polarize film it's just to reflect the light which falls on the screen. Polarize film is that thin film which is glued on top of the lcd. You can also use aluminium duct tape. 😊

Nice Talent thank you

superb bro !!❤🔥

Very smart hack. I’m just wondering if we can do away with the silvery film altogether. I can see the numbers just fine after the silvery film was removed in the video..

Gotcha, I will try this too...I ll get back once done

use polarized film ( can get from broken lcd computer screen) instead of Al paper, to get much better results. Anyway thanks for your video .

very nice thank for you

Great brother

Keep it up sir :)

Great content

It's reallylity show ❤❤

Nice video brother keep it up

Thankyou ❤

good work bro

hello! i found your video very useful. can i ask if it is okay to use aluminum foil to replace the film?

Tqq so much bro

Good job

Good.

Nice bro 👌🔥❤️

Nice maan ♥️⚡️💯

AWESOME

Xcellent

Keep it up

Hi! I’ve used the polarize film but as it shows on the LCD, the first 3 numbers was showing/clear but when i try to input another numbers, it fades. I have not yet replaced the battery and i just saw the comment to use reflector rather than the polarize film. Is it because of the battery or the film that i have inserted which shows fading numbers in my sci-cal. Thanks!

super bro

Thanks

Good job bro🔥,

can you use aluminum foil as an alternative for the silver paper and polarized film?

Does this work for all LCD displays like printer, copier, coffee maker too?

I use white photo paper and it works good 👍👍

do you have a video tutorial in half number in lcd issue casio fx100ms?thanks

Does it work for the other model where digits are made by dash lines. I have some missing dash lines on my calculator

tyyy

How u attached that silver paper to the lcd? Glue or something? Can i use whitepaper instead? ;

You can also serve kitchen aluminum foil ???

Hey do i have the same problem my lcd looks like its leaking from the top the calculator looks like the thumbnail for this video if i replace reflective film will it look good again

Is it ok if I use different alcohol such as isopropyl or ethyl?
