Hey,
first of all i´m from Germany, so my english is not the yellow from the egg!
i hope you can help me.
On my Switch OLED the Joycons not charging and the Fan isn´t working. But if i inject 5v with my lab bench power supply to the Fan+ it starts spinning and the joycons are charging. I measured only ~1.5v on the Fan+ thats not enough. In this Forum i found a post about it so i bought some ALJ/ALZ Chips from China. I already desolderd one put a new one on but still only 1.5v.
i already tried to bypass this with a small wire from the battery to the output of the ALZ Chip, but then when i turn off the Switch the Fan runs at 100%, so this solution isnt usable…
Can maybe the m92 be broke? I cannot measure a short around it. Maybe there is something else i miss?
Fan is working with 5v injection and Joycons are charging. Without injection its only 1.5v.
ALZ/ALJ Chip seems to be okay i tried 2 new one with both i got the same result like with the original chip.
Thanks
