I would like to start a new thread on this, See if someone can help me figure out why I have no 24V or 5.3V outputs
What I know,
All of the Electrolytic Caps have been replaced, with good quality low ESR
I have 391V DC across the large capacitor
I have a good stand by voltage of 5.2 V
When the front power button is pushed I see a PS on voltage of 3.2V
There is no 24V 0r 5.3V noticed on the power supply.
I have given the P/S a good looking over; nothing is jumping out as being faulty.
From some of the other threads on this monitor I think the F9222L controller is responsible for starting the 24V.
These are the readings I get on the pins of F9222L referenced with pin 8 as ground
Pin 4=0V Pin 7= 19.54V Pin 10= 4.94V
Pin 11=4.6V Pin 12=4.94V Pin 13= 3.03V
Pin 14=.7V Pin15=4.93V Pin16=.011V and
Pin23= 391V
I have attached a schematic from another thread that is of the power supply I am working on.
