The smt resistor coding used is this -

So far I have not found the transistor marked A66
I thought it would be something like a high current version of a 2N7002

may be a
FDN337N - MOSFET Transistor, N Channel, 2.2 A, 30 V, 0.065 ohm, 4.5 V, 700 mV
is closer to what we are looking for

could you post some wider pictures to see more of the circuit connections
to see what its connected to
usually I expect resistors to go high resistance when overloaded and semiconductors to go short circuit
