    Holy Crap! My TI 30Xa had something like this displayed .... didddiii instead of 888888. I was missing an attachment to my soldering iron so I carefully pressed the iron on a small wad of aluminum foil against the ribbon area. I carefully ran it across a few times. IT WORKED. I was about to chuck my 40 year old calculator before running across your video. I know it's only a $10-15 calculator, but it made my day. Thanks Dude!

    Hi! Thanks to you, i fixed a similar problem with my fx-992s. In my case, the problem was found on the LCD side: some of ribbon cable pins has lost a contact with the LCD. I fixed it using the soldering iron. At first, i fold a piece of aluminium foil to make 4 layers. Then this foil have been applied above the ribbon cable upon the area, where it's connected with the LCD. Then i heat the foil using my soldering iron (150 C degrees), and following its tip i move some silicone card to apply some pressure. My fx-992s is working again! Thanks a lot from Ukraine!

    Thanks a lot sir for an idea!
    I have tried heating and pressing but did no good to me (i guess there isn't much adhesive left on my board),
    so i tried a different approach.
    I took a piece of soft material and placed it on the top of that problematic spot. It works like a charm!

    Just tried this with the iFixit iOpener, first time I was too quick to apply pressure, second time i had something else apply pressure and i let it sit for 10 minutes, then applied some extra pressure with my fingers afterwards and VOILA! I could really feel the contact point being hotter after letting it sit with the iOpener on it. Thx for inspiring and doing the quick show and tell!

    I just found 2 Casio CQ-82 alarm clock calculators. Boxed & probably never used. I stuck 2 batteries in but the displays are very faded. Is there a way to repair or replace them? They look ultra retro cool & I'd happily give one to someone who could fix one up for me.

    What is the name of the tool you used? Is it a soldering iron, but you’re only using the hot air and not making any contact with the components? If I don’t have one, would a hairdryer work?

    • @SevenFortyOne
      @SevenFortyOne  10 หลายเดือนก่อน +3

      It's called a hot air rework station. A har dryer probably won't get hot enough. But a hot air tool you can buy at a hardware store or maybe harbor freight might...I'm not sure

    Firstly, thanks for the video. However, I'll let you know if that if you use a potato laptop, the 720p60 is unplayable. TH-cam has, I believe, stopped distributing 720p30 videos where 720p60 is available. There are firefox add-ons that occasionally work, but they're unreliable. Since we're talking about reviving old hardware I figured I'd let you know (and yes, I realize it's 2 years ago but whatever).

      @@SevenFortyOne Do you mean by clicking the gearwheel? If so, it doesn't have 720p30 as an option if 720p60 exists, and sometimes 480 (or even 360 if 480 is not present, which happens) doesn't have the appropriate resolution for certain videos. However, if firefox has a way to default to 720p30 on youtube that would be awesome... I _assume_ you mean the first thing, though.
