I found the 5H0165R completely burned, capacitor C31 swollen connected on pin 3 of the 5H0165R, zenner diode ZD4 in short that is connected on pin 4 of the 5H0165R and the zener diode ZD1 connected on pin 6 of the L6561 in short of 20v. In addition to these components there is a resistor that powers the 5H0165R (pin 3 (VCC)) that is roasted, I just don't know its value.

I need to know the value of the resistor R60 that is connected to the vcc pin of the 5H0165R, I think it is 1R or 18R.

10-18R will be fine.

I wanted to see another question, at the moment I can't get the 5H0165R. I would have to buy but looking for parts in the workshop I found the 5L0365R. Know if I can put the 5L0365R in place of the 5H0365R, if so, do I need to make any changes mainly in the resistor that goes to the regulator's VCC?

5H0165R 100kHz
5L0365R 50kHz
So, you can't replace H by L. (need to change transformer, snubber). Resistor on VCC 10-18R (the same)

You can replace 5H0165R by 5H0365R

thank you very much for the information and clarification
