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.
