Scientific Atlanta representative should be contacted.

The temperature of the modulator stabilization circuit is out of
specification. The board should be left for at least 1 minute to see if the
error clears. If after 1 minute the alarm still persists then the card
should be removed and re-inserted again. If this action does not clear
the alarm then a Scientific Atlanta representative should be contacted.
This alarm clears when the communication is established with the
device.
<X> represents the QAM card position and <Y> the RF Output
number.

fans are working again the alarm clears.
