Hello great team!

I'd immensely appreciate the help of brilliant minds out here.

I've Solar rechargeable emergency unit that can power 2 lights and a small table fan. The unit stopped working with a blown resistor on the circuit. I did try replacing the resistor with an identical color coded one but never paid attention to the type of material (ceramic/Carbon film). All I am trying to get is the fan working by powering by unit through AC (direct w/o a battery). I'm a noob and need help who can figure out what's wrong with the circuit and help me accomplish this.

I have attached pictures of what the PCB looks like.

Other specs that may be of help:

Mains AC : 230v 50-60Hz
Solar Panel : 12v 0.7A
Fan : works fine off a 9v battery or 9v 850 ma adapter

This will be of a great help to me. Thank you very much!
