回答先: Can I repair a Texas instruments TI-5135I don't know if you can even get a new print head anymore, that calculator is over 30 years old! You may be able to get by with cleaning it off though. There's some tutorials on YouTube, one video I found used 99.5% isopropyl alcohol and a tooth brush: https://youtu.be/QWD5iwWl_MI?t=14m34s Hopefully your calculator prints the same way. Unfortunately, I have no idea how to take it apart nor how to get to the head. However, those old machines normally are reasonably easy to disassemble so you can probably figure it out. Sorry I couldn’t help much, however if you run into any problems I’ll still try to help! Just comment to this answer and please share some pictures if you can; pictures can really help diagnose what’s wrong or what needs to be done.

回答先: Why is my calculator screen disappearing?If this only happened right after you cleared the history, then it’s not the display, you just need to do a RAM reset. (Take out the backup battery and one of the AAA batteries. Hold down ON for 10 seconds, then put the backup battery back in lastly, put the AAA battery back in.) It may also help to reinstall the OS. Since that’s a more complex procedure I’ll refer you to this video that explains how to do it. If this has been happening over the course of days or weeks then it’s definitely either display issue or a battery issue. You can try just replacing the batteries but it that doesn’t work then Nick’s answer will help you out.

回答先: My screen is hard to see when looking straight at itAdding onto what TheYootx Media Group said, another possible issue is the contrast was turned down too far. You can easily fix this by (make sure the calculator is turned on) repeatedly pressing [2nd] then the up arrow until you can see the display again. If this doesn’t work then it’s either a battery issue or a display issue. If there’s a display issue, then this article may help you repair it.

回答先: My calculator doesn't turn on anymoreHi, thanks for including all that information! I think TI-84 Plus CE Recovery Techniques. is what you’re looking for. Please comment if you still can’t get it working and I’ll keep trying to help! P.S. The charging light is separate from the main calculator software so it can still charge even when the main calculator is frozen or broken.

回答先: How long of a screwdriver do I need to open this calculator?I hope I'm interpreting your question correctly, but if your screwdriver is too short, then just getting a longer one will work. It does require a T6. Have you tried looking at the disassembly guide? TI-84 Plus Disassembly

回答先: Keeps Turning Off and On, Even after chargingOk we may need a little more information to help you. So is your calculator boot looping? Is it turning on and off repeatedly? Or is is just turning off after you turn it on? Does it keep misbehaving while charging? How long after you turn it on does it take before it turns off again? How long after you turn it off does it take before it turns on again? Does taking the battery out an putting it back in help? Do you have something stuck in your I/O port? (the thing that looks like a mini headphone jack) Does reinstalling the OS help?

回答先: My calculator sometimes turns on an works fine, other times doesn'tI don’t believe it’s a display problem, I’m fairly certain those lines are just from the calculator booting up. However you can test this by taking your calculator (during the time when it refuses to turn on) and plugging it into your computer (Note, you may need to install TI Connect CE). If you computer recognizes that something was connected, then you’re right, it’s most likely a display issue. If you computer doesn’t recognize that something was connected, then it’s a different problem. My guess is there’s a loose connection somewhere under the battery compartment. You can follow this repair guide to take the calculator apart (though you don’t need to take out the motherboard) and see if you can spot any loose or dirty connection points.

回答先: Is it possible to increase the ram on the ti-84 plus ceTo elaborate on Austin’s answer: Not only are they soldered, but even if you have the experience to desolder the RAM and replace it with compatible, better RAM; the calcuator’s operating system couldn’t even utilize it. TI designed the OS to rely on having only 256kb of RAM. The same goes for the Archive storage as well. You wouldn’t get a CPU clock boost either. If you want to increase the speed of your TI 84 Plus CE, there are a few programs that can help. One such program is the Advanced Wait State Change[|r] I wrote that reduces the wait states of the calculator and can make it up to 30% faster.

回答先: Why my charging light is always on? It kills the battery.EDIT: If you’re someone who’s also having this issue, I would suggest looking at Nick’s answer where he suggests replacing the battery, it’s a much easier possible fix than what this answer is about to describe! Wow I'm surprised, judging by your answers, this probably is a hardware issue! (DrDnar helped me with this answer) His best guess is that your power supply sent a surge of electricity that fried your driving transistor (basically it’s the thing that controls the LED). This could happen if you’re not using the original charger that came with the calculator. Unfortunately, to repair this, you’ll need some pretty hefty experience with fixing circuit boards and a good hot-air rework station which can cost upwards of $500. :( (If you have the experience and equipment to replace it, I can try to get some steps on how to do it.) If you don’t want to go through the hassle of returning your calculator or fix it, you should be able to just sever the LED connections from the circuit board. You’ll still be able t...

回答先: iPad 3 Apple Logo Reboot LoopHi! It sounds like you’re having a very similar issue to iPad 3 cycles apple logo when on charger, shuts off when disconnected., perhaps that thread will help you! A good thing to note is the iPad 3 has a wide range of parts and fix guides you can see by going to its product page.

I think you should add the phrase “JBL Spot” somewhere in this guide. Although I searched the web and iFixit, this guide didn’t come up because I was searching for JBL spot rather than JBL spyro.
That moment your recognize your colleague’s dog in the last photo.
P.S. You can buy spare mini USB ports from sites like Amazon or Ebay.
Hey louis liu, I updated this guide with a link on where to buy the battery. It cost about $12 USD on Amazon: http://a.co/d/iTK2V0v
Fine, it’s your guide. :)
Hey @ajcooke01 I noticed you changed the images back to the old TI Connect. I’d like to know why since I believe people should really move away from the old TI Connect and use the new one. The new one still works with the TI 84 Plus and is a heck of a lot faster and easier to use; especially for new people. I really think this guide will benefit from people using the most recent TI Connect since it has better community support and is easier to use.
Jeez this needed a lot of work to fix! But I think I made it into a much better, more robust guide. It’d be great if you’d post this in the correct TI 84 Plus Device page. Also, please do more research about your guides and pages before posting them. People like *quality* guides, they don’t care if you’re pumping out tons of low quality, duplicate, or poorly researched pages. ;-)
I don’t believe you can buy the motherboard anywhere. However you can salvage them out of other damaged calculators.
