I've been experiencing a similar bug or glitch with my switch Ig recently where my switch screen would be on but wouldn't appear on tv, it's been happening for over 2 years? since 2021, I got this switch around mid August of 2018 so for about 5 years or so and never had this happen to me before. It still charges and works fine, I don't think the dock is broken at least I don't think so? Idk. It only started working recently around April to May this year where I would dock the switch and the screen would appear but then shut off after like a 1min or 2mins? after a few minutes of troubleshooting later it actually lasted longer than a minute! which is new since it never lasted longer than 1 minute, but then shut off around 11 to 12 ish mins. Before it came to where if I even touched the switch the screen would just shut off, I tried everything to re-seating the switch to soft-resetting, unplugging both cables for over 10mins and nothing worked, the only 3 I haven't tried are getting a new HDMI cable, switching to a new TV or getting a new dock... which is a lil too expensive for me atm. so i'm really stuck rn I've been trying to find people with a similar issue of mind and finally found one here at Ifixit. Lets hope Ifixit and fix the hell out of my switch since idk what to do. [Btw my TV is a TCL Roku if you were curious] I also have another small issue that occurred a few months ago where when I put any Joycons on the switch they wouldn't connect, Does anyone know why that happened? it works now tho, also my left Joycon side rail has a screw that is super loose. Can't recall any other malfunctions with my switch, Other than this one. My switch still functions properly I haven't gotten anything too serious which is good. so I think thats all I have to say for today, It's nice to have finally explained? Ig about my issues, anyway bye lol.
