omg i've been reinserting the battery for a few times and is still not turning on until i open up to only discover the cable is disconnected. thanks for the video!
If your Casio scientific calculator is only working with solar power despite having a new battery, here are a few potential reasons and solutions: Possible Reasons Battery Installation: Ensure that the new battery is installed correctly. Check the orientation (positive and negative terminals) and ensure it is seated properly in the battery compartment. Battery Type: Confirm that you are using the correct type of battery as specified in the calculator's manual. Some models require specific battery types, and using the wrong one can lead to malfunction. Battery Contacts: Inspect the battery contacts for corrosion or dirt. Clean the contacts gently with a soft, dry cloth or a cotton swab. Corrosion can prevent proper electrical contact. Solar Panel Issues: If the solar panel is functioning but the battery isn't, there might be an issue with the solar panel itself. Check for any obstructions or damage to the solar cells. Internal Circuitry: There could be a problem with the internal circuitry that manages power from the battery. This might require professional repair.
Possible Fixes Reinstall the Battery: Remove the battery and reinstall it, ensuring it is aligned correctly. Test with Another Battery: If possible, try another new battery to rule out the possibility of a defective replacement. Reset the Calculator: Some calculators have a reset function. Check your manual for instructions on how to reset your model; this can sometimes resolve issues. Use Solar Power: If the calculator works with solar power, you can continue using it in well-lit conditions while exploring other options.
Hello, is there a way to fix the sine, cosine and tangent keys? What happens is that when you press the keys they don't work and if it is possible to fix it, please or should I buy another one?
My calculator is very dim in battery power, i changed new battery but same issue, checked continuity test, continuity is perfect, then checked output power on board, it shows 1.48, so everything is fine, but display is dim... and the calculator is fine with solar power, the issue is in battery power, any solution sir??
Look you’re familiar with electronic test knowhow.It might be voltage issue inside the board circuit.Difficult for me to advise without see the board condition.
I’m using soldering iron and solder lead to repair the wire connection.A soldering iron is a hand tool used to heat solder, usually from an electrical supply at high temperatures above the melting point of the metal alloy. This allows for the solder to flow between the workpieces needing to be joined. You can use anything that is able to heat a piece of metal up to the melting point of your solder (between 400°F / 200°C and 700°F / 370°C). Butane lighters work the best. But you can also use candles, oil lamps, alcohol burners, or even open camp fires.
I lost my Casio calculator and found outside on the road, rain fell on it and I opened it to dry it It worked and after I left it to dry it didn’t work anymore
Check the battery is put in correctly and not with reversed polarity. Check the battery is new and in date. Clean the contacts of the battery holder. Check for damage to the battery contacts

Hello Please what of in a case where the battery is not up there but in the middle of the calculator, where there are no wires, what do I do? I have a Casio fx-991ES Plus and an fx-350MS both with the same issue. They only turn on when I remove the battery and put it back.., but the power-on button doesn't turn the calculators on
Hi ! Thanks for watching.Possiblity There a many issue ,one of the issue is button contacts at rubber key. You may refer below link video as reference.Hope may solve your issue. th-cam.com/video/otetUUaaHJM/w-d-xo.html
Black wire (Negative)connect to the battery supply at negative terminal.Calculator in this video can’t power on is due to black wire is disconnected from battery supply.(No supply voltage to the calculator). Note: Red wire (Positive supply) Black wire(Negative- Gnd)
Got 2 wires for battery connection to board.This wire supply voltage 1.5V from battery to board.If broken, possibility no contact and cause calculator can't power on.
The tool use is called Soldering Iron.Beside it,you can use Candle or Lighter to melt the the solder and stick the wire connection back.Also can use super glue to stick the wire contact to solder of battery terminal.
Use un soldador y plomo. También puede usar plomo de soldadura y un encendedor. Si tampoco tiene las herramientas, puede torcer el cable manualmente hasta el pin de la batería.
Thank you, I had the same problem with my calculator and tomorrow is my test in calculus. Thanks for the Vid!
You’re most Welcome! Good luck for your test….
I'm also facing same situation but when I screwed it open the problem is exactly, same you're video helped me a lot thank you

Thanks for the nice video. I check the wirings using a volt meter. The lines are okay. But the calcu still wont work. I need your help thanks
You're most welcome!
There a many possibility cause can create the problem ,try to check the power key contact first.
Calci only works in sunlight even after changing the battery
You mean same problem.No different before and after change the battery?
@@TonaziTube yes
@@TonaziTube when I flash 📸 on the solar panel calci turns on

You need to open and check the board if want to repair it.May be got a break circuit connection , contact or carbon issue at the button area.
Eso lo hiciste intensional, es demasiado fácil de hacer
Esto es realmente lo que le pasó a mi calculadora. Verdadero problema al compartir
Thanks a lot 🙏
You’re are most welcome
I disassembled mine and discovered that the ground wire was corroded, so I stripped it and soldered it, as shown in the video.
Thanks for sharing your experience!

I lost my Casio calculator and found outside on the road, rain fell on it and I opened it to dry it
It worked and after I left it to dry it didn’t work anymore
May cause by deffective of electronic component inside.
My calculator somehow can be used again after i opened the case...
but still thank you for teaching me how to open the case!
never mind the ground wire is also corroded
Hope you can solve it
Can I used any kind of glue to fix the wire?
You can try super glue
Thank you for this great sharing
You’re most welcome!
Thanks bro you save me
You’re welcome Anis…..
Bro i brought dr smartx calculator at flipkart last month now it's not working. Like not turning on can u pls help and guide me what to do
Did you check and confirm the battery voltage?
No bro
I think should I open and check the connections of wire or should I change the battery
Bro pls reply
Pls do simple way first.Replace the battery.
bro in sunlight calculator is working but When Replaced new battery not working
Check the battery is put in correctly and not with reversed polarity.
Check the battery is new and in date.
Clean the contacts of the battery holder.
Check for damage to the battery contacts
Can we use super glue to paste that Wire?
Can use super glue but pls make sure the copper wire have a good contact to the solder of the calculator pin.Otherwise it will come out again.

Ma quel cacciavite , in quel modo spuntato , perché non lo butti e te ne compri uno nuovo ?
Acquista già un nuovo cacciavite😆
What if the black wire got separated?
Black wire (Negative)connect to the battery supply at negative terminal.Calculator in this video can’t power on is due to black wire is disconnected from battery supply.(No supply voltage to the calculator).
Note:
Red wire (Positive supply)
Black wire(Negative- Gnd)
Need to connect red wire and black wire to complete the circuit of voltage supply to calculator.
Ka booommmm
😀
Bro what if the wire is broken from the board?
Got 2 wires for battery connection to board.This wire supply voltage 1.5V from battery to board.If broken, possibility no contact and cause calculator can't power on.
Thanks bro
You’re most welcome
Naaa, what is I don't have that burn tool to repair😢 struggle a lot
The tool use is called Soldering Iron.Beside it,you can use Candle or Lighter to melt the the solder and stick the wire connection back.Also can use super glue to stick the wire contact to solder of battery terminal.
Tq so much bro 😎
Welcome Sir!
👍
Thanks for watching
Bhai mere ka on button kaam nhi kr raha hai
dekhane ke lie dhanyavaad. krpaya any taar kanekshan ya baitaree star kamajor jaanchen ya nahin.
Thanks for watching.Please check other wire connection or battery level weak or not.
@@TonaziTube all perfect but only on button not work
Could be a variety of problems, more than likely a worn or malfunction of the key circuit.
Como soldar un cable. Perdida de tiempo!
Use un soldador y plomo. También puede usar plomo de soldadura y un encendedor. Si tampoco tiene las herramientas, puede torcer el cable manualmente hasta el pin de la batería.
@@TonaziTube cambia el título de la publicación...te lo dice un técnico en electrónica.
Its turning and when I put take and put battery but once turned off can't on 🥲
Maybe got connection issue inside the calculator.
What if digits in display is not visible?
Need to check battery continuety first.
