Recent changes to some of the frequencies used for Spanish TV may mean that you are receiving a "NO SIGNAL" message when trying to watch some Spanish digital TV channels.
One of the more popular Spanish TV channels affected is Teledeporte, the free sports channel on TDT.
Basically, some of the TDT channels have changed frequencies.
So all you need to do to get them back is to rescan, normally using the "install" options on your TDT receiver.
This should scan all the available frequencies used for TDT and your channels should then reappear.
This may not be the case for some community systems, where additional "frequency modules" may need to be installed to receive these new frequencies.
