-
Remove the 2 screws (13mm, 6mm head) connected to the plastic piece holding down the power cord.
-
Then remove the additional 4 screws (13mm, 6mm head) and 2 screws (11mm, 5mm head) securing the base.
-
Carefully lift the base up from the rest of the blender.
-
-
-
Remove 4 screws (11mm, 4mm head) connecting the circuit board to the base.
-
-
-
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.
-

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.
Does somebody know where can I buy this circuit board ??
Anyone know the chip on this circuit board?? Proprietary I assume??
Great info but i’m looking to purchase a replacement circuit board for my ninja blender and can not find one. Any ideas?
hi,, i need to know the reference of transistor with position Q2. in the main board BL770 , thanks.
