I'd try to fix my Switch myself rather than sending it to Nintendo, that's for damn sure. If it was something I felt confident about. I've modded my fair share of consoles, swapped all transistors in my SNES etc. Installed plenty of modchips. I recently put in a samsung note 4 battery with bigger capacity in my Vita and it worked without issues but I decided to replace it with a new official Vita battery again because I wasn't confident enough in my own soldering. I didn't want to risk the solderpoints coming off the battery if I accidentally dropped it somehow. That can cause sparks and worst case scenario - fire. I've got no clue about the Switch internals other than the disassembly videos but if there was something I thought I could fix I'd look up youtube and forum guides first. I sometimes see people complaining about their broken Dualshock 4 triggers as an example - rightfully so - and having to send them to Sony for repairs. I had it and fixed it myself and feel sorry for those who aren't able to. I'm not an engineer but if you know what's broken there's a chance you can fix it yourself. Just bought an underwater camera for ice fishing. There was a piece of paper stuck between the lcd and outer plastic shell. Losened the four screws and tried to take it apart. Didn't work. It felt glued together. I emailed the company tech support who said that it shouldn't be glued and then I easily opened it with a razor and fixed it. I see people complaining about the Dualshock 4's joysticks wearing out and yeah..they SUCK. So I bought the kontrol freek CQC classics at the time of ps4's release and since then I've been using my controller for ps4, pc and now my switch and they're fucking amazing. I put in the piece of foam in my joycon controller but I also soldered in a long wire as an extra antenna on it. There's a video for that too.
