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.
Hi Tom:
My BL770 turns the button on and off as soon as any button is pressed. To turn it on again, it must be disconnected. What could be the damage? Thank you.
Hello . Did you find the pcb anywhere?
Are you have pcb nijnja blender BL685.How much price??..
