The voltage regulator is located on the other side of the PCB in a large DPAK housing. I could not read it all because it is placed between 2 pcb's but it start with LM293.... probably a 2937 and it shows 3.3 so a 3.3v version. You can measure over the other capacitor if the voltage regulator is still alive.
i looked up the lm2937es-3.3 datasheet ( check my photo album) and it says that there should be an input capacitor and an output capacitor , the cap that burnt on my pcb was the input capacitor and it should have a capacitance of 0.1 mf , as for the output cap, it should have a 10mf minimum capacitance.
how come the input cap on your pcb is 10 mf ? shouldn't it be 0.1 mf since it also uses the lm2937 ldo?
