[addalmr]

hello thank you for accepting me among you
I have an acer aspire 5733 pew71 la-6582p laptop which does not start if I press the power button, no LED is lit when plugging it into the mains socket, but the pq96 circuit heats up a bit. Can you help me?.please

Now to check some voltage’s PQ52 PQ53 all pins ? PU17 all pins not down correct
PL48 PU1000 all pins supply ?

pq52 pin1 to pin8 18v
pq53 pin1 to pin 4 18v / pin5to pin8 0.71v ;pl48 17.2 v both pin , pu1000 4.5v both pin

about the PU17 it is a 24pin circuit with the values written below:
pin 1 ---> 5.48v
pin 2 ---> 1.32v
pin 3 ---> 0.37v
pin 4 ---> 4.57v
pin 5 ---> 0.01v
pin 6 ---> 0.00v
pin 7 ---> 0.01v
pin 8 ---> 2.29v
pin 9 ---> 0.22v
pin 10 --->0.38v
pin 11 --->0.06v
pin 12 --->0.03v
pin 13 ---> 0v
pin 14 --->0v
pin 15 --->4.87v
pin 16 --->5.16v
pin 17 ---> 0.71v
pin 18 --->0.69v
pin 19 --->17v
pin 20 --->17v
pin 21 ---> 0.71v
pin 22 --->0.70v
pin 23 --->2.56v
pin 24 --->18.25v

PQ52 pin4 18V ? if so PACIN not generating this is the fault, test 1st 2 fets for short then trace back PACIN this is your gate pas to switch voltage
