Nintendo Switch Lite - Known good diode measurement
Ғылым және технология
Test a faulty Nintendo Switch Lite with the diode readings of this known good working mainboard. Start by testing a component in the circuit and compare the diode values with this known good diode values.
If the readings are significantly different, it suggests a faulty component.
Set the multimeter to diode mode. Red probe to ground, black probe to the component that you want to measure.

One thing missing from your Nintendo Switch Lite videos is an in-depth on the 29-pin connector. It'd be nice to get to know where those pins lead for a precise repair. For example, I got a Switch Lite which has an interesting fault, the left stick only moves vertically, not horizontally. So, instead of reworking the entire connector, I could focus on the pin that's used to listen to the left stick's horizontal input and see what's wrong with it. Anyway, keep up the great work.

Hi i did made a video on it on my channel: kzread.info/dash/bejne/c4Nk3MuIpcmfabg.html Gr. Jim

@@fixmyappjim I'm sorry, I should've been more specific. I meant the 29-pin connector *from the daughterboard.* You did mention the pins from the main board connector, but you left out the pins from the daughterboard connector.

@@Rodox2k10 Ok i get it, yes indeed i left this one out my focus was on the mainboard :) Gr. Jim
Great video, did a similar thing on a my working lite with photoshop ;)

Yeah did it also but is more work then making a video :) Gr. Jim
Thank you! Mine are only off less than 10% on most of them so I won't worry too much about that. The resistance measurements on the apu concern me on mine. Not sure if it's fried yet as I've got to test the battery properly first.

Great video! Some of my diode readings are off. How many counts or % += would be acceptable before a cause of concern? Im using the USBC connector as my ground at all times.

Thank you for watching. It depends on the multimeter, temperature etc. I usually check if a components has a low or very high diode readings if it is more then 1V difference i would check that area. Gr. Jim
