Good evening ladies & Gentlemen.
Few days ago, i received a rather old switch (with an HAC-CPU-10 board) which refused to do anything.
Once finished checking the usual suspects on the board, i found out that the 1uf 16v 0805 mlcc next to the BQ24193 was shorted to ground.
After switching it for a spare one, the short was gone and the console was charging (both in handheld and docked mode),
but won't show anything on the Screen, yet the Touchscreen would work and even sound would be played upon touching the screen and/or disconnecting the JoyCons.
Tried two additional known working screens, but they wouldn't work either.
The only thing i'm getting is a working backlight and the above mentioned working sound.
Double and tripple checked the components around M92T36, BQ24193 and P13USB,
but none of them seem to be faulty.
Since i'm running out of ideas (and since i haven't found any additional shorts),
i'd know like to ask you if you've got any ideas on what might be wrong with this particular switch.
Any Help would be highly appreciated

PS:
I'm currently awaiting a shipment of the three chip's i've mentioned above,
so i can't test if it'll be fixed by swapping them right now.
