Hi everybody
I am new in this forum and repairing laptops on component level.
My laptop toshiba a665-14c with motherboard LA6062p v4.0 is total dead , no lights
I changed 2 mosfet already PQ7 and PQ8. I changed 4407A tot mosfet 4407 .On Test point 2 i have 19v but ont test point p3 i have 0,2 v. Also i measure test pooint p3 to ground(massa) abouth 78 ohms.
I remove resistor Pr45 to see it came from the battery but no result.
So i mesure all components around but i found nothing shorted.
Can somebody help me? I have no scope only multimeter. I have schedule v2.0 from motherboard but it look me the same.
Please help me to fix my laptop.
Best regards
Steve
