I put the original resistance back on, I continue to have a maximum of two volts on the 12v which then goes away and I again have the short on the 5v and no sign of voltage, we are ready to go
take that brown goo off (between that green and yellow cables) that brown goo can get conductive over time and messes things up. So anywhere you see this brown stuff, remove it.

ok, anyway it is a kind of glue that they put initially, a bit I took it off, but do you think the problem is on the primary or secondary?
I found a power supply to buy the same for 10 euros, if I can't solve it I can do some tests with the working one, meanwhile in the afternoon I try to understand where this short comes from
I can't see much of a problem on the output side, bedsides the -5V and -12V having two extra (smaller) diodes per rail and that is about it.
So I guess the feedback circuit next.
I always have the short on the 5v that does not go away, I removed the heatsink with the schottky diodes I removed the inductance, and the short remains, I have to see what else to remove to understand where the short is on the 5 volts, in the previous message I wanted to tell you that I bought a second hand equal power supply to help me solve
no, the resistance was good at the end, unfortunately I got distracted and I thought it wasn't good, instead I measured the same one in a working atx and it's good
I'm trying it on the outside, by bridging the green wire with gnd, I've tried to disconnect all the resistende, capacitors and zener diodes that are on the way of the red wire but the short does not go away
