loss of channels. PVR 9200T?

If the Auto-tune does not work or the 9200T does not always record after retuning then you need to delete all TV channels and delete all Radio channels and then manually tune.

Crystal Palace main transmitter numbers for retuning until 18th July 2012 are 22, 23, 29, 32 and 34. After that they are 22, 23, 25, 26 and 28.

If you receive channels from another transmitter, or one of Crystal Palace’s relays, then follow the instructions in that link for how to find out the numbers.
