The 1u53 reading sounds correct for capacitance of C155 (1.5uF).
C=capacitor
15=pF digits
5=multiplier
15x(10^5) or 1 500 000 pF.
The A478 (if cap) if using the same method would be 47pF x (10^8) = 4700uF!!
Obviously too large for the small SMD component.
Thinking that 'A' could be "anode" of diode??
Except that the white band next to A (if diode) will be cathode.
Have you diode / cap tested the A478?
As "47" is a standard value, meter should show near this in whatever mode, then round it to 47.
Resistor? = 4 700 000 000 ohms = 4700 MΩ (not likely)
Cap? = 4p7 47p 470p 4n7 etc...
Semiconductor? = the A478 could just be a part number, like 1N4148.
