Usually they just don't start spinning, some of the NOAA ones have been going for 25 years and haven't ever lost orientation.
The satellite in this post is a russian one, they don't have an analog transmission anymore, this image is from digital transmission near the frequency of the NOAA analog one, so still easy enough to recieve.
But as for the analog NOAA transmission, There really isn't any reason to shut down the analog transmission, the satellite was built with enough power to run it, so shutting it down would just lead to a surpus of power on satellite. I don't think the design would even allow pushing more power on the digital signal.
NOAA will have some huge tracked dishes for this to get a perfect image even with the lowish power level.
Also, the satellites with analog are not the main ones anymore. NOAA has some new satellites with much higher resolution imagery that are not nearly as easy to receive as these older ones. they only broadcast at 8GHz instead of the 1.7GHz or 137MHz that the current ones do
