2D scanner failure

We have recently purchased six turtlebot3 Burger and the 2D scanner on one of the robots is not working.
It turns on but does not produce any data. SO the rostopic is empty.

Hi @weria!

So if I understand correctly, you have five functioning scanners and one, that seems to be broken?

Have you tried to use one of the others on the not working robot, to check, whether the scanner itself is the problem, or something else?

Hi Weria,

thanks for your topic and sorry for reading your are having issues.

May you could tell us if you are having LDS-01 or LDS-02?
@Tahir @willson do you have any idea?

Hi @weria
Can you please share the log as well as rostoplist list, rosnode list and output for ls /dev/*
