  • Hi, in this tea break fix we have a 1975-1977 Casio pocket calculator that has no power. It was sent to me by a viewer called Gordon. It has had battery leakage, and even though it has been cleaned up, it is still not working.
    Link to the unofficial Facebook My Mate Vince Fan Club (right now this is the only one 🤣) groups/17476...
    I now have a PO box here in the UK, so if you would like to send something in that MAY be featured in a repair video, then here is the address. No items will be returned, so only send it in if it is of no value to yourself.
    PO Box 2597
    Watford
    WD18 1HT
    UK
    I don't think couriers send to PO boxes so in the UK it would need to sent via Royal Mail.
    Remember that this is just for entertainment and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things. I do love fault finding and trying to fix broken things, so I hope that comes across in this 'Trying to FIX' series. Many thanks, Vince.

    Another fab video Vince. I recently bought a Rechargeable fan from Amazon and it turned up broken. Amazon refunded me for the price of the fan and told me to dispose of the damaged product. For the first time after watching your videos for years, I decided to take the fan apart, fault find with a multimeter and desoldered a faulty capacitor. Found the replacement part on eBay, put everything back together and it now works an absolute treat. Thanks for showing us all that we can recycle things and do our part to reduce electrical waste! :)

    VFD. I bought a 1974 Casio with VFD 2 weeks ago from a car boot sale for 3 euros. All it had was some corrosion on the battery contacts. Quick clean and works fine. Though the power switch may need a slight clean too.

    I knew you’d be able to fix it easily. I did think it would be the switch due to its location next to the battery compartment, but I haven’t got a clue about soldering etc, so I thought I’d send it to the only man I know who does. Great fix and looking forward too some more in the future. Gordon 😊

    45 years ago, these devices were invaluable for students. Although, I suspect they were looked down upon by most maths teachers as it was standard practice to show your, 'working out', rather than to rely on a machine to do it all for you. Of course, it was only the more well-to-do students who had access to such devices, anyway, as they weren't exactly cheap when they first came out.

For the nerds to confirm pls that it is a vintage year '1975'. Tyvm!!!

They love to explode inside vintage macs and in PCs of the time they slow leak eating away at everything that comes into contact often eating traces while seeping between the layers of the pcbs.
