Went as far as running without the zener and no change. The to-220 tests fine on the diode setting on my meter so its back in circuit. Double checked my voltages and all the + and- 5 volts are present. The 12v pin only gets as high as 3v before it falls due to the instant shut down.. Swapped the 1000uf@10v e-caps with an exact set of used ones. I dont have an ESR meter, I am using a centech #69096 digital meter if that helps reference my tester and its functions...
The dc-dc sub board mentioned gets to 14v before the shutdown...
any other culprits on this board i need to check??
