Red and Green Led flashing

After last update (3.1.22/1.1.3), the led is alternating between red and green. The trainer connects by Bluetooth and ANT+, and it gives speed, cadence and power metrics, but the resistance control is not working.

The Tacx Utility App testing dashboard reports an Under Voltage Fault.

Is it possible to do a firmware rollback?

I tried with different cables, and I'm not using a power strip as suggested by Garmin (https://support.garmin.com/en-US/?faq=G6Px1OlYKD7qPpF4j4KIS9). Also I checked different power outlets, and tested…

Now saying that, tried this morning and back to the original problem. Tried your fix again but it hasn't working this time. just stuck with the red/green flashing light. hopefully Garmin respond to my email!

It's a shame much time without a solution! With my Flow useless due to this problem, out of curiosity I decided to see "what's inside" with some destructive testing. This pitiful failure and Garmin's response made me switch for the competitor's brand.

Hi,

Appreciate this post is a few years old but how did you manage to get the cover off the turbo unit? I have removed the 2 screws fixing it to the turbo legs and the smaller bolt in the plastic casing but cannot see how to split the two parts of the device.

It feels like there's a lot of resistance or is just a big pull needed? Don't want to damage any internals by being too rough.

Thanks

This might help, the two halves of the plastic casing have small tabs to join them together, pressing the inside half will disengage the tabs and allow the halves to separate. See support link below for pictures.

Thanks for the reply

I passed my unit off to a fellow club member and repair cafe expert who managed to get in with ease. He fixed the blown resistor but looks like something else has blown.

Hopefully get there in the end....

Hello! Do you have any details on how you physically went about this please? Having the exact same issue!!

0 pokemonjohn over 1 year ago in reply to 1615868

See my post from page 1.

I show which resistor I changed and what I bought.

Yes thanks - mine has popped too! How did you go about actually installing the new one on the mboard? Thanks! And the link you provided - do I have to buy a pack of 50? Lol!
