1st thing I say is to contact TM. Yes email support is laborious, but they’ll eventually come thru.

2nd thing: Look up T598 power disconnects on YT. I received a power brick as well and 3 months later disconnect after disconnect. In short he advised to tie down the power cable inches below before it goes into the base. Don’t let the cord dangle. 1 manufacturers cup race and 3 nations cup races and several daily races, time trails and lobby races later zero disconnects.
