help tracking a short

[david watters]

so to start i have repaired/modded consoles since the ps1 and have repaired countless switches. i have my personal V1 here thats never had a problem until now. it was working fine and my daughter was playing just dance, she went to dock the switch and as soon as she did the green light flashed 5 times and now the switch is dead.

all caps on the pi3usb are shorted to ground, removed it and still shorted. the m92 had a single cap shorted, removed it and all shorts are still present. removed bq and still the same.

any ideas what else could cause this?

While I could take a guess..
(there are certain components that break easier, M92T36 etc)
but there might jus be a surrounding fuse that blew, which you already checked for

I'll instead recommend watching the switch reapair videos by

He usually comments everything he does and is a really nice individual :-)

I will never touch any electronics on that level as I'm inept.
But if you feel up for it. Good faith.

PS: "Green light flashing" yields this

yeah all fuses checked and when plugged into a usp amp meter im stuck at .47 amps

well 3 switches now before i found out it was this dock killing them. luckily the last 2 are under warranty still atleast, i just lost my only v1 console lol. so the dock will charge just fine but as soon as you power the docked switch on the screen flashes and the system is completely dead.

all 3 consoles show as unrecognized usb device when plugged into a pc and have shorts on the caps under the p13usb even if that and the m92. 2 of them are being shipped off to nintendo under warranty but id love to get the v1 running again. just starting to seem like the SOCs were killed then as i cant find and shorts.....
