Hey Jacobo . From what I'm seeing here, you have blown the metal-oxide varistor (MOS) (the light brown ceramic capacitor looking thing), which could be your savior. It's designed to protect against excessive over voltages. To fix it, you'll need to buy a new one and replace it. I'd also replace the EMI suppression capacitor (the big yellow capacitor behind the MOS), as its physically damaged. This guide shows you how to solder and desolder; How To Solder and Desolder Connections
Just as a precaution, I'd test the big brown ceramic capacitor behind the EMI suppression capacitor, the 47 ohm resistor and the voltage regulator at the least. As for if you can convert it to accept 240VAC, no. The board is built to only take 120VAC and as its power supply is only a linear one. You'll need to buy a 120VAC - 240VAC converter.
This guide covers testing capacitors; http://www.electricaltechnology.org/2013...
This one covers resistors; https://www.google.com.au/webhp?sourceid...
and this one (though harder) covers the regulator; http://www.learningaboutelectronics.com/...
I hope this helps you out or at least sets you in the right direction. If you have any questions, please feel free to ask.

I need to replace the MOV in my NJ600 as well, but I'm not sure which MOV to order. Anyone know what the ratings (voltage, current, etc) are for the MOV? There are no visible markings on mine. A part number would help too! Thanks.

i have a similar problem, but plugin into a voltage converter on 50hz power in Europe. the MAS blew when powering the device on. This could be a pro blem with the transformer I am using. Panasonic 1500 transforming adapter type that says it is not good for circuits., when i measure the outpuit of the transformer I get 24 volts AC when plugged i nto 220, and my voltmeter will switch to DC for some reason, leading me to believe the panasonic unit somehow must sense a high resistive draw in order to supply the full 110 volts? I understand that the MOS is sensitive to voltage spike, not current spike so I seems like it would work on 50hz? maybe in this system I have used it allows a spike in voltage of some sort. any help would be welcome. I would like to replace the MOS and try with a stable transformer.

we did the same for our ninja coffee maker. but we can’t figure out how to pry open the unit. any ideas?

Hi I've done the exact same on my ninja blender/food processor
I can send the find a new Capasitor for it
It says 7N271K on it an on the bottom it has 322+
What do I need
Thanks

@Stefan. different blender, different layout. you do want to start your own question and add plenty of images of the damaged components etc. so that we can see what you are seeing.
