I changed the M92T36 already. The Switch used to not even boot. Then I changed it and now it boots. Changed the bq aswell.Seems that you have a short between the cap and ground, somewhere along the line the current is getting shorted.
I would start with the M92T36 since this is involved in managing power. if you can replace it, try, if you dont have a replacement to hand.. maybe make it dance with hot air and flux and see what happens?
if known good is in, and still shorted, then yes, go for PI3USB
Good luck!
so did you managed to get it going?I changed the M92T36 already. The Switch used to not even boot. Then I changed it and now it boots. Changed the bq aswell.
wow !!! that is quite something, I saw one like that for sale in eBay (uk) and it was too expensive to go for it so I did not bid on itLol... Look at this!

try the usual.. check if works in docked mode, get the mobo into a known good assembly and check if the same issue appears, if it does.. then is either the video timing chip or Video chip
check the voltages across to make sure they are "normal"
Interesting to get to know how you progress with that one
are you getting 3-6v on pins 5 and 6 of the Mt92 chip?It boots and everything works but it does not charge.
also check how much voltage comes out of that coil next to the BQ chip... maybe is not stepping the voltage up enough to charge the battery.With a plugged in battery iam getting battery voltage on them I think (have not checked lately.) I also changed bq already.
ive never seen it either but you seem to have covered must of the "usual" so your case may be unusual..The coil only carries the battery voltage and the switch does not recognise the charger at all. I'd think it has to do with the port but I can connect the switch to the pc and push payloads and such.
As I have never heard of the coil going bad ('' it's never the coil") does that happen a lot with he switch?
@Borega
When you plug a charger into the switch
Check the voltages on BQ24193
Pin 1 VBus should be high 5v-15v depending on charger
pin 2 if using the nintendo charger this pin should read low
pin 3 Should be low 0v
pin 4 should be low if charge in progress, if this pin is high charge is complete or disabled, if this pin is alternating from low to high this could indicate a fault.
Nope. With a normal usb charger I get about half a volt.
Anyone have any experience with blue screen consoles? I bought another round of broken consoles and stumbled upon one. I haven't poked around inside yet, just wanted to understand what others have experienced with blue screens.

FWIW, I was able to recover a stuck in logo console the other night. After testing literally every cap and checking voltages all over the board I was desperate and decided to bake the board....they are the worse ones.. most probably the NAND, MEMORY or the TEGRA chips are either damaged or corrupted.
so far.. I have NOT been able to recover any blue screens or stuck in logo consoles
they are good donors tho ! LOL - normally all the other chips are good to pull
