title_body: Taranis x9d plus se 2019 malfunctioning My taranis suddenly stopped working properly. When I turn on the taranis it does not read my crossfire module anymore (sometimes the crossfire turns on/off randomly) and then the taranis screen goes blank.
  The taranis is still on when the screen goes blank. I've replaced the internal 3v battery and the issue still continues.
  I've also made sure my connections are connected properly.
  What is the best way to troubleshoot this?
  Where can I buy spare parts such as a backboard or front board for the taranis, cannot find a vendor in the US.
upvoted_answer: Sounds like a hardware issue, you might want to RMA it to FrSky.
