Hello! :D Background / Information: My laptop sometimes gets really hot, the CPU goes up to over 90 degrees Celsius (not...

It's most likely the charger or the port on the headset that's worn or being filled up with dust, making it have a bad connection. I would start with really carefully cleaning the charger port on the headset, start with turning the headset off and then carefully trying to get the dust out using some type of needle or something else that's thin. Then I would try using another charger, the headset seems to be using a micro USB charger. Not too long ago all Android phones used this kind of charger, and most other small electronics still use this port as well. So you probably have one available at home to try out. If it doesn't work with another charger, it's probably the charger port on the headset that is bad and would need a replacement. I can't really say if it would be easy or not to replace this. But come back if this seems to be the problem and someone will try and help you solve that! Good luck and hope this helped! :D

First of all, you will need to clean everything with water damage/corrosion, I would recommend using some 90%+ (preferably 99%) isopropyl alcohol and a toothbrush to carefully clean everything. This is because the corrosion may cause short circuits etc. If it doesn't work after that, you will need to do some more diagnostics using a multimeter to try and find where the broken circuit is. I'm not really into this kind of troubleshooting yet, so I can't really give you any help regarding this. Good luck and hope this helped! :D

This probably won't help, but it's worth a try. And that's cleaning them, preferably with 90%+ isopropyl alcohol. If that doesn't help, you will probably need to replace the whole joy-con, I don't really know how it looks in the Quest Controller but I'm 99.9% sure that it's using the same design as everyone else. So you may need to figure out how to get it apart yourself. The problem is in the design where after some time the surface in the joy-con that the signal goes through is worn off and loses contact. Hope this helped! :D

I can tell you that it's a Torx bit, but it's hard to see what size it is and I can't find it online. But I would guess the bit size is somewhere between T3 to T8. Update: Thanks for the documentation, they are M2 Torx4 (T4) screws. From my understanding, the "L" just means that it's one of that L shaped tools normally used for Allan/hex keys. So a normal T4 bit should work without any problem.

The problem where your fans etc. starts and sound works and the screen is black, but when you shine a light at the screen you can see what it should display is caused by the backlight for the screen isn't working. There are multiple possible causes for the backlight to stop working, it can be everything from the lights in the backlight being burnt, to corrosion from water damage at connectors or in the worst-case water damage to logic board/components. Start With Cleaning / Checking: I would start with opening the laptop up and looking for corrosion after the water damage, then clean it up using 95%+ (preferably 99%+) isopropanol and eg. a toothbrush. Check the connectors to make sure that they're not loose. Replace the Screen Assembly: If non of the above helped, you will probably need to replace the screen assembly. I can't promise that this will work since there could be damage to the board, but this will most likely solve the problem. MacBook Air 13インチ Early 2017 ディスプレイアセンブリの交換 Hope this helped and...

Since you have power in the charger it's a bit hard to say what else it may be caused by. I would start by following these steps provided by Asus on their FAQ page. Asus Support - Troubleshooting Hope this helped! :D

Make sure that you use the correct sized tri-point bit. When unscrewing, try putting a bit more downforce to prevent the bit from coming up from the screw as easily. If the screw already is a bit striped, try doing the same with the next bigger sized bit and this may help you. Just remember to be more careful when using the wrong sized bit since it may strip it even more if you don't get a good grip from the start. Hope this helped and good luck! :D

The SIM card is what you use to be able to connect to service (3G, 4G, 5G) as well as what is used to send SMS and make phone calls. You can still use WiFi, but other service doesn't work without having a SIM card.

One of the most common problems that cause the display to go black and still have audio is that the so-called "backlight" breaks, this is what makes the light for the display. To see if this is the problem, turn off the lights around and point a flashlight on the screen, can you see an image where you point the flashlight? If you see the image, it's the backlight that isn't working. The TV you mentioned seems to have LED strips for the backlight, if the problem is that the LED strip is broken it should be solved by replacing these LED strips. If the problem is caused by something else, it's harder to say what you can do to fix it. Hope this helped and good luck solving it!

When the printer prints small dots like you described instead of one continuous line it is most of the time caused by under extrusion, this means that the printer isn't feeding enough filament to the hot-end/nozzle which results in the printer not extruding the amount of plastic needed to make a full line. Initial Troubleshooting: Here I will mention a few smaller things that you should look at before trying the other solutions. Start with checking your slicer settings, maybe you have the settings for another material that has a lower printing temperature? Was the material that you used last time a plastic with a higher temperature, if so you may need to extrude some extra filament at a higher temperature before the new filament reaches the nozzle. Solution 1 - Extrusion Gear: One common thing is small filament particles building up over time in the gears pushing the filament forward, thus ultimately causing the teeth of the gears to be filled up and they lose the ability to grip the filament. If this is...

It was a while ago you wrote this, but I will reply in case you still have the problem or anyone else is reading this in the future.
