Mains voltage to low

My tacx Flux smart is blinking red/green light. In the tacx smart training app it says: Warning 6.10, Mains voltage to low. Does anyone knows how to solve this problem?

There is no tacx support in brazil...

hi, as everybody here, I have today the same problem warning 6.10 with my tacx vortex . I work in electronic device and I decided to open the vortex a the power side. I found 2 or 3 components which had…

I am happy to report that replacing the mosfet did seem to have solved the problem. The device starts up correctly and provides resistance without showing any errors.

The mosfet is a B12NK80Z which is easy to source.

I hope this might help someone coming across this thread in the future.

In total i replaced the 2W6o8J, the 3R3 resistor (twice) and the B12NK80Z. The first two I sourced from digikey (part no. A106032CT-ND & A102528CT-ND), I ordered the B12NK80Z mosfet from eBay.

Here is an image of the parts I ended up replacing

I have the same problem but I can't find R65 - 2W6O8J (SMW26R8JT) and I replaced it with standard resistor with whisker 2w 6.8 Ohm. But this didn't solve the problem - I still see the problem with low voltage on main board. Could anyone with any advice to help me with this problem plz

Did you replace or check that the mosfet (B12NK80Z) is fine?

I ordered the R65 replacement from digikey, part# A106032CT-ND

But it seems that Mouser, Farnell and RS have stock as well.

I replaced 3 components: 2 resistors and MOSFET

Hmm, did you have the burnt out components before switching? You might also have a completely seperate issue on your device...

Yep. First of all I noticed smell, blinking red/green lights and error in the app - low voltage. Then I dissembled it and found out 2 resistors that were burnt out - R65 and R66

Okay, sorry, just wanted to make sure. Does sound like the same problem. I am afraid i don't know how to help you at this point. After i installed the new mosfet, everything ended up working fine again, no errors in the app.

Before i replaced the mosfet, the two resistors were burning out again within seconds after plugging in power. So if that is not happening for you, you are probably having some other issue (now and/or from the start)
