Hello everyone
I am fixing this hp 250 G5 laptop. The motherboard is dead . There is 19V but 3v and 5v are not present.
PU2 wich is a rt8243a dc to dc converter gets 19 volt on pin 11 but there is no output on 3.3v and 5v pins also 3v, 5v always on not present.
PU3 does not get 19v.
Resistance to ground on all coils are as following :
PL202 10MΩ
PL602 0,7Ω
PL1206 21Ω
PL1205 9Ω
PL1203 8Ω
PL11 196Ω
PL9 0,7Ω
PL8 26KΩ
PLV 1 67Ω
PLV2 30Ω
PLV3 28Ω
PJP2 is shorted to ground
Could anyone help me out here?
