Hey I have this same problem. If you are inside of the US you can get a replacement at ubreakifix. If you would like to do the repair yourself you can order on on amazon or Alibaba. Personally I am not comfortable ordering one of these so I am choosing to go the repair store route. I am yet to find out but in all honisty if it costs over 40$ I will end up ordering a new dysplay and move the broken one to somewhere where you cannot see the screen but still use it as a voice assistant.
Cheers
