ASUS X541U motherboard : x541uvk rev: 2.0 no picture

Hi to all
Asus X541U
cpu : I3 GEN7
VGA: Geforce 920MX
motherboard part no: x541uvk rev : 2.0
problem: no picture

According to the picture, 4 parts were corroded. All of them were replaced no change
3.3 and 5 is ready and lop top on /off normally.
when power on:
pl9100 ,pl9101 no voltage
pl8102 ,pl8101 no voltage
pl8302 =1 v
pl9301 no voltage
pl8600 no voltage
pl8901=13 v
please advise me
tnx


It should be noted:if sort pin 3,4 pq8807 and pq8810 ....+3.3vs and +3v Appears pq8811

Hello!

- Measure the resistances to ground on all coils.
- Measure the voltages to ground on pins 7, 8, 9, 12, 18 of chip PU8600, when the machine is turned on.

hello matic
pu8600
pin 7,8 =0
pin 9=19v
pin12=5.13 v
pin18=4.6
pl9100 ,pl9101 =24 ohm
pl8102 =15 ohm
pl8101 =11.7ohm
pl8302 =100 ohm
pl9301=420ohm
pl8600 =300 ohm
pl8901=about 1m ohm
current consumed when device is on =0.04 amper

How about the resistances to ground on coils PL8701, PL8702?

- Measure the resistances to ground on pins 2, 4 of chip U0401.
- Measure the resistances to ground on all pins of diode PD8600.

- Measure the voltages to ground on all pins of diode PD8600, when the machine is turned on.

U0401
pin 2= 21k
pin4=1Mohm
PD8600
1=53k
2=86k
3=72k
PD8600 voltage:
1,2,3 all zero
PL8701, PL8702 res= about 11 kohm
please help me

- Measure the voltages to ground on pins 4, 14, 18, 19, 22, 35, 57, 66, 82, 83, 85, 86, 96, 111 of KBC chip in the following cases:
a) Before pressing to the power button (machine turned off).
b) After pressing to the power button (power LED is turned on).

- Measure the voltages to ground on pins 11, 12, 21, 67, 69, 70, 74, 106, 108, 109, 112, 127 of KBC chip, when the machine is turned on (power LED is turned on).

Now disconnect the power supply, wait a few seconds, reconnect the power supply and perform the following measurements:
- Measure the voltages to ground on pins 56, 110 of KBC chip in the following cases:
c) Power button released.
d) Power button pressed.
