Thanks for the post… this is helping me with my blender…. by any chance do you have a better picture of the resistor on the back of the circuit board… it seems to be a yellow blue blue gold sequence resistor… my board just burned that resistor and I am trying to find and replace just that resistor if possible… but I am not sure of the colors so I can locate the right now.
Anyone know the chip on this circuit board?? Proprietary I assume??
hi,, i need to know the reference of transistor with position Q2. in the main board BL770 , thanks.
