820-2914 green light OK, fans spin, no chime

Hello everybody,


I got a MacBook Pro 17 early 2011, 820-2914 with fans spinning that does not chime. No signs of liquid damage.


PPBUS_G3H is 12.53V

ALL_SYS_PWRGD is 3.3V


Any ideas?

With no RAM and with battery only, I get quarter fan spin. With no RAM and with charger I get a 1 beep loop. PPVCORE_S0_CPU is 1.149V

Dead GPU of course.
