What would cause my blender to not register its power supply?

It's a Ninja Mega Kitchen System blender, model BL770, used lightly over three years. Not a single hiccup. Except, this evening, when I plug it in and press the power button, the button doesn't light up, nor will the blender function. It's tried half a dozen power supplies throughout the house, but for some reason the power isn't going where it should go. I don't know if that means there's a loose connection inside the case, a short, or maybe the circuit control board decided to crap out on me.

Has anyone had this problem? Does anyone have an exploded diagram of the blender and electrical schematics? How do I go about ruling out possible causes?

I used a multimeter and screwdriver circuit tester and followed the wiring junction by junction. Initial check of the plug's prongs indicated the circuit wasn't closed. The circuit only closed once I wired it to circumvent the motherboard. So the motherboard is bricked. And I have never used a soldering iron, let alone own one. So it's a question of whether getting a new motherboard, soldering iron, wires, and taking the time to get it right is cheaper than buying another blender.

Hi @brazenandbold ,

If you have a DMM (Digital MultiMeter) you could use its’ Ohmmeter function to perform some initial tests to try to localise where the problem is.

With the blender disconnected from the power supply, place the meter’s test probes across the two pins of the blender’s power cable plug and check if the meter shows a reading.

If there is a reading then this proves the power plug and the cord are OK.

If there is no reading then you may have to open the blender and prove the wiring between the plug and the connection in the blender where the power cable is terminated, to prove which wire may be faulty etc.

The blender will most probably have to be opened in any case whether you have proved that the power cord is OK or to find out why it is not.

Here’s a link to the ifixit Ninja Mega Kitchen System BL770 guide, which may be of some help.

Once the blender has been opened, it can be inspected for any obvious problems such as burnt out or heat stressed components. Looking at an image of the motherboard from the guide there doesn’t appear to be any fuses in the blender so that rules that possible cause out.

As stated, these are only the initial steps, after that it may come down to doing point to point testing of the circuit or testing of individual components, which, with out a schematic diagram (I can’t find one online) won’t be easy.

if there any components that you are not sure of, post some close up pictures back here and hopefully someone will be able to help. Here’s how to do this. 在已经存在的问题里加入图片

Hi @brazenandbold ,

It may be difficult to find a replacement motherboard anyway.

If you can't find one and you want to pursue it further post some pictures of the motherboard(as described above) and perhaps someone make pick up something that you missed or advise you how to test the board
