What to do if the Revopoint mini is flickering and warming up?

when I connect the scanner, it warms up and after a while of scanning with for some reason poor tracking, half of the blue beam starts flashing furiously, leaving the other half working. My skanner is Revopoint mini( sorry for the bad english)
