complete Ded set want turn on. measured the
power jack 19v in
Dc in PL24 vin ok 19v schematics P 35
PL46 - 0V (3VALWP Absent)
Pl47-0V(5VALWP Absent )
PQ101 - leg 1- 0v leg 2-18v leg 3-0v
schematic P 38
PQ 100A-100B -0V legs
I have a question here is PQ 100A-PQ 100B leg 6&3 gives the voltage to the PU1000 IC ?
what does mean VL ?
schematic P 38
JLED1 power connecter
pin 1-3VALW Absent 0V
pin 5-3VS Absent 0V
but pin 7 ON/OFFBTN#-17V in
is their a short ? power button should get only 3.3V?
Schematic P 32
for the power button SIO chip gives power U16 chip
is the pin 32 U16 SIO chip Shorted?
Schematic P 30
