Ill limit you with the boring details, but I have an electronic device that I can attach to my bike tire and it produces power and in return it can apply resistance to my wheel to simulate a steep hill or I must produce a certain number of watts. Its a great tool for training....
I heard a pop and then took apart the unit to find a burned spot on the PCB. I later found the fried SMD melted to the inside of the plastic housing. Looking at everything, I found a part number for the replacement resistor and I plan on ordering that first. Ive never had to solder or mess with SMD parts before so I need advice on what to do, and what not to do. Im sure this was caused by an over-voltage, but Im extremely green, so if anyone can tell me what I should be checking out in addition to the resistor it would be greatly appreciated. Finally, what should I do about the hug burn on the PCB?
Replacing the PCB is more than I have to spend, so I have to repair it.

Recap:
I burned a resistor off the pcb, I want to repair it, what else should be checked, how do I clean the huge burn?

 

Pcb cleaning fluid and a tooth brush will shift the burnt marks,if there is no damage to the tracks, just replace the resistor, otherwise you will need to repair the copper tracks. As for testing other items, transistors and diodes using a dvm on "Diode test" will do.
