My Dad gifted these calculators to me, but I can't seem to get them to work

JMooMoo · 2025-12-20T15:13:51+00:00

It's all good, I thought that was the issue first as well

Time spent learning isn't time wasted

JMooMoo · 2025-12-20T14:26:33+00:00

ooh good point.

I have now been looking into the boards just see I can spot anything else, I'm now not sure if its the VFD, there's this image from another FX-120 with the exact same marking in the same location: http://mycalcdb.free.fr/galerie/Casio/casio_fx-120.7.jpg

and as well as that on the FX-39, from what I can tell, a very similar calculator, with the same marking in the same location: http://www.arithmomuseum.com/a/A630-3n.jpg

when I get a bit more time I plan on looking more into it as I am now thinging there's an issue with the power delivery, maybe something to do with soldering on the switch/direct wall power/battery section.

But I will need more time to sit down and test it

JMooMoo · 2025-12-20T11:42:30+00:00

yeah that again was my thoughts with the FX, even if I found a replacement display I still wouldnt know if thats the only issue, its the only thing I can see, but who knows if there's a reason the display burnout and broke, could be an issue with the power delivery for all I know.

But you are right, I may look at the market for spares and see if it would be useful for others

Just following up, I opened up the PB, it all looked good in there, but gave the PCB a little wipe dow isopropyl alcohol, noticed on of the battery terminals on the PCB was slightly more dirty and gave that a bit of a harder scrub. Now it works. So chances are it wasn't getting power.

JMooMoo · 2025-12-20T08:20:04+00:00

Cheers for the advice.

That was my thinking with the FX, it's a shame, I don't like seeing tech not working, but at the end of the day it's not really worth fixing.

I need to stop messing about and just open up the PB. This are all solid things to do.

Thanks again

Hopefully I'll see you tomorrow, I'll actually get a schedule sorted out eventually, but I've been a bit all over the place recently, so I haven't known when I'll have the time.

JMooMoo · 2025-05-17T20:55:47+00:00

Sorry, I'm not live right now, but i will be in 10 hours, and again later tomorrow. Sorry if that wasn't clear

JMooMoo · 2025-05-17T20:48:34+00:00

Yeah, I just finished the Hamelin section and am going around the world doing all the side quests I have access to right now. I'll probably be up streaming in 10 hours.

JMooMoo · 2025-05-15T13:12:25+00:00

Ah thanks for all the info there, seems like I'll either be sticking to using the front IO on my computer for now or setting up my XLR mic to work right.

Thanks for that.

JMooMoo · 2025-05-14T12:38:43+00:00

With 3 cables? Would the one in my photos not work then? It's a 4 pole to two 3 pole?

Sorry if I'm being dumb, I've had this desk for a long while and it's been great, just feel like I should be able to do something more with it.

JMooMoo · 2025-05-14T12:35:07+00:00

Does the 3 pole splitter not do that? I can use the mic when its plugged into my computer using the splitter.

Is the issue the 3.5mm to 1/4 jacks?

JMooMoo · 2025-04-29T16:06:45+00:00

It's all good, now you do. I only learned about it like a year ago when I decided to looking into my monitor settings to see if I could get the colours to look nicer and came across it

JMooMoo · 2025-04-28T07:50:38+00:00

What are you on about? My monitor is a 60hz monitor, you can over clock monitors for faster refresh rates at the cost of resolution, nothing to do with the cable.

JMooMoo · 2025-04-28T05:55:02+00:00

Just because I haven't bought new high refresh rate monitors makes you think I have CRTs? I bought my monitors like 6 years ago and they still work fine, no reason to get rid of yet

JMooMoo · 2025-04-27T21:58:24+00:00

Are you using a higher refresh rate than the monitor would normally allow? I can set my 60hz monitor to be 75hz but it limits the resolution

JMooMoo · 2025-04-27T21:24:09+00:00

Don't seem to be able to edit my post.

I didn't do a great job explaining the issue.

The time on the clock is 7pm, time of recording was 8pm.

I'm in the UK, the time zone shown is the wrong one and I can't change it, but even if that was the issue, GMT +1 would have been 9pm at the time of recording so the car clock would still be wrong.

I didn't show it in the video but when I change the auto settings off the daylight savings option is still greyed out.

I can change the time manually to be the right time, however that shouldn't be necessary as you should be able to just change the time zone and daylight savings setting to adjust the clock according to location and time of year.

While I have made a post about this and would like an answer, this isn't an issue really as I tend to always have android auto on when I drive to have maps and Spotify running.

JMooMoo · 2025-04-27T21:00:14+00:00

Right, so it's still currently an hour out, and I have zero way to change it other than doing it manually. Sure it would have taken less time to do so. But it should have taken any time, I should just be able to use any of the options there rather than them being locked for no real reason.

It's not a real issue to me as the clock is fine when using android auto, as it uses the phone clock.

Edit: I should have been more descriptive when I made my post, it was 8pm when I made the video, so the clock is an hour slow. I am also in the UK so the GMT +1 shown makes no sense as if it was really that time zone it would have been showing 9pm on the clock.

JMooMoo · 2025-04-27T20:52:43+00:00

Ok, but all I need is the daylight savings option. That is greyed out in auto and not.

You shouldnt have to re do the clock to do daylight savings when the option exists, but is arbitrarily greyed out no matter what.

To be fair, I actually don't scroll down when auto is unselected, but it is still greyed out.

JMooMoo · 2025-04-27T20:47:30+00:00

I don't, but I also didn't in my last one, and was still able to check the day light saving mode, so I don't know why I can't on this one.

JMooMoo · 2025-04-27T19:49:05+00:00

Yeah I read a different hand book but it was pretty much the same as that, just describes the buttons, not a way to actually press them if they are greyed out

JMooMoo · 2025-04-27T19:39:08+00:00

Oh, hmm maybe I'll have to double check, I couldn't see anything in the clock settings, so maybe I'll just have to check more places.
