Hey All,
I have 2 OG switches, and a switch lite with various problems. The 2 OGs don’t charge, but will power up if I charge the battery externally. So me, sounds like both have failed M92’s, but would love to have a diagram to print out so I can easily write out values. Is something like that available somewhere? Plugging T-824 in, I see a low value on pin 05 on one (0.13v) and on the other switch everything green (though pin 05 on that one is 0.31v, which certainly seems low relative to the other values). Both of these switches came from same person, so it’s reasonable to believe they used the same bad charger and killed both. Both USB-C ports look fine.
The Lite… was charging and then threw up an error which I should have paid more attention to, I hit okay, it shut off, and hasn’t turned on since. But plugging into power, it seems like it’s powering on and charging, just no screen response at all. No shorts arounds M92, but having some info on where to start would be good. I’d guess power rails? Plugging a little T-824 into the USB-C, I don’t see any shorted pins, but pints 08 and 17 are open, which may be expected for the Lite. USB-C port looks fine.
Any help would be greatly appreciated.
