What is this part that seems burned? Resistor? It has about 280ohm of resistance but it doesn't look like resistor. Anyway I can confirm that pcb describes it as R2 which means that indeed it's a resistor. So it a special kind of resistor or just destroyed?

It could easily be a resistor, and even a good one. Sometimes oddball parts look like that and have no markings. While measuring its resistance, hold it in your hand while watching the meter to see if it's a thermistor. Reverse the leads to see if it's a diode.
Why do you even care? Replace it with a 270 Ohm resistor and see if the unit works.
