    • Remove the five screws (13mm long, 6mm head) attaching the Base Cover using a Phillips screwdriver (Ph2).

    • Remove the two screws (13 mm long, 6mm head) attaching the Base Cover using a T10 screwdriver.

    • Cautiously desolder all the wires connecting the circuit board to the unit.

    • Carefully slide the circuit board free of the wires are place the new board in.

    • Solder the wires back onto the new board, keeping track of which wire goes where in order for your unit to properly function.

    Hi,

    I would like to know the specification of the metal oxyde varistor MOS as I need to change it.

    Thank you

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.

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.
