Vancouver

Not a game console, but I had a PC hard drive repaired at Sortek Electronics in North Vancouver repaired a couple years ago and was super happy with how he ran his business.

I went in with My Big Idea and the owner took a closer look at what had failed and proposed a different repair that required less labour and was less likely to fail. I think I had it back in 2 days.

If you want someone competent, I'd for sure give them a call and inquire to see if they deal with Switches. I also had the feeling that wouldn't attempt a repair on anything they weren't confident they could fix. That was important in my case because my failed hard drive was the sole backup of a bunch of precious old photos.

My buddy just went to a Nerd Collective to get an old hard drive recovered, I'll ping him and ask where it was he went. He's near Kingsway and Vic, and from how he was talking it weren't that far from him.

Edit: the website

Is the problem especially technical? Anything less than soldering will remain in your capable hands. Just need to order tools, spare part, and watch a youtube video. IFixIt has a great kit. There are other nintendo specific ones you can order, although IFixIt includes all nintendo related screwdrivers as far as I know.

With 0 skill I replaced my Switch fans. Had to, no way I would risk that chip getting installed.

Lots of very friendly tutorials on youtube. Give a few a peak now and get a feel for if you think you can. You'll save a lot of money and learn an invaluable skill for our future.

I'm surprised to hear they're repairable and not just throwaway.

You probably need a general "electronics repair" shop: A place that can source parts & tools, and has staff that can break down, solder, and rebuild things with circuit boards.

Put that into Google Maps for some nearby options. A lot will advertise their services in the context of more general home appliances like TVs or PCs. Give them a call first to check if they have the parts and knowledge for your Switch. If they don't, ask if they know someone who does. I suspect the hobby electronics DIY space around Vancouver is probably fairly close-knit.
