If before turning to close PJ41 on PL10 VCCGT appears 1.2 V
and accordingly, if to close before turning on PJ40 appears 1.2 V (0.8 V is once again a/ must be 1.2V ) PL9 PL8 VCORE.
NCP81151 pin.PWM must be 2V.
NCP81203P PU9
- pin6 VCORE_PG=3.3 V on PU10 pin6 VCCGT_PG=3.3 V
PU9 NCP81203P
Pin 27 VCCSA_VBOOTA/ADDRA ? sets the PWM voltage limit
PSYS Pin 29 ?V generates charger pu1, probably something like there is power.
pin12 H_PROCHOT# 1.6 V signal about accident on the temperature
Why not have VCCGT and only have VCORE VCCSA 1.05 V
If PU6 close PJ36 the PL7 is 0.8.
Could the graphic chip make damage VCCSA or kbc ?
* Resistance VCCSA relative to the ground 17ohm
check all phases of power supply, closing and PJ40 PJ41.
Pre-open PJ13 and 42. PL5, 8, 9, 10 and 11 should stand at 1.2 V.
PL6, PL7 it" supply for video chip
jumper pj42 + pj13 not open .
On PL5 always should be 1.05 V/ PL5 VCCSA 1.05V
*CPU odpowiada za obraz na wszystkich wyj. sygn.
check all phases of power supply, closing and PJ40 PJ41.
