Hi,
Like anyone knows, there is no schematic available for power supply 5062-8229.
I look a HP8564 power supply schematics, and it is quite same bacically.
This is just information for anyone who have problems with this.
It seems that problem is on the Buck Regulator control board.
NE5560 is not working, or some protection is jamming on/OFF SIGNAL for this ctrl ic.
If I succes to repair this, I will tell you.

I've also had a problem with power supply 5062-8229 recently:
a tantalum capacitors connected to +15V was burned. I changed it but it didn't work.
I appreciatte if you could send me the schematics of HP8564.
Thanks!
