Hello Everybody
I m working on 820-3023 come with no green light problem. When i checked eyes saw a lot cracked capacitor on CPU VCore and other place ( only capacitor) when checked voltage PPBUS_G3H is 16.5V (should be 8.4V) After replace Q7030,Q7035,U7100,R7021,R7022 PPBUS_G3H is turn back 8.4V and green light come back.
But now PP5V_S5 and PP3V3_S5 not come back this voltage not get enable signal
( replaced U7200 also)
PPVRTC_G3H is 3.3V
So do you think also dead U1800 or U1000 ? Do you spend more time repairing for this board ?
