48v / 3A 110vac power supply that was connected to 220vac

accidentally it was connected with the wrong voltage at 220v, which caused the burning of 2 MJE13007 transistors, fuse, 2 C1815 transistors, 2 2.2R / 2w resistors and 1 220uF / 250v electrolytic capacitor (shorted). After replacing these components, the power supply even operates, but the cooler does not rotate and the output voltage of 48v has a DC voltage close to 50v and an AC voltage around 120v. The LED on the FULL panel lights up green without the battery being connected to the output, the correct thing would be to turn red and light up only when the battery is fully charged. I am thinking that the integrated located at the entrance of the HS108P-J source code (it is that it is a photoaclopador may be damaged). If it is a photoaclopator, the problem is that this component is not found here in Brazil.

components marked in a circle were the ones I already changed

The HS108P-J is a controller and most likely it is programmed for different needs, even if you find a new component, you still need to program it. Look for more, maybe you missed something.
