i have Hp cq61 which has short +VIN to ground.
M/b is DA00P6MB6D0.
I removed PR61 and on +VIN side it is short to ground.
i checked PQ6 and shows that D is short to groud. i removed PQ6 and i still
get short to ground on pin 5,6,7,8.
i checked pin 2 with pin 8 and i get .485v.
i checked capacitors connected to drain with ESR meter and are shown ok.
checked PQ49 and D is short. checked pins 2 and 8 and i have .585v.
Gates are not short on any PQ.
checking all capacitors with ESR meter are shown ok
+VIN is the input of TPS5147A that goes on pin6.
removing TPS5147A i still get short on pin 6 which is the input (+VIN)
can someone HELP!
