This board has no liquid damage at all .
the PPBUS-G3H was 0 v and shorting to ground .
i found that U7210 was very hot when i injected 5v .
took the U7210 then no more short At PPBUS.
solderd new U7210 now I get 13.05 v at PPBUS with charger only
and 13.01 with battery.
pp3v3_g3h 3.410

no image on screen or external monitor .
cpu is hot when press the power button , get light on USB data cable .

External video?
If you can confirm 100% USB activity, check some voltage at LCD connector.

 

[suzukigsxr1000r]

No video on external and when I plug the charger never give
me the ring sound that is charging
speakers connected .

PRAM reset tried/done?

 

[suzukigsxr1000r]

Did PRAM nothing change .
cpu just warm bit even left for long time still not hot
fans never spin after awhile .
as I mentioned when plus the charger the ring sound
never there .
is there any pin need to check on the U7210 which I replaced .

 

[suzukigsxr1000r]

When plug charger !!

 

[2informaticos]

Check voltage on all coils.

 

[suzukigsxr1000r]

When I disconnect the touchpad cable from board the fans
start spin loud obviously because touchpad not connected
but that’s mean board turns on !!!
cpu cold

U7210 being shorted means the CPU got 13 volts and this is done....

Then cpu barbecued !!
fuuuuuuuuuu wasted whole day !!
