Replacing A Game Cartridge Reader In A Nintendo Switch Without Taking The Main Board Out. 

We have with us today a Nintendo Switch that won't read game cartridges anymore. We've tried the simple solutions from Nintendo like clearing the cache, cleaning the contacts with alcohol and power cycling the Switch. None of that worked so we're going to replace the reader itself.
We're going to attempt to do this repair without taking the main board out of the housing. It shouldn't be a problem as there is enough room to do so.
Follow along to see how this repair is done and to get detailed instructions!
