I had all the same problems as well and figured it might need to reload the channel map, so I went to Standby until the clock time reappeared and then power cycled.
For 530's, this is the safest/preferred method of causing a reset.
At least place into standby until clock comes back and then you can front panel reset.
The reason for the extra routine is to force any outstanding memory writes to flash and clear the buffers.
I still have low ebno (1.3) on WGN HD and get RED on Z, the first 8PSK signal from a few weeks ago.
When I check 270/271, just black with Green lock, but in Options 6-4 it shows the channel # in the windows tab as 000, WTF???
Also show channel 000 in diags as well, so I think the Motorola code is screwed as ANY IPG menu's show correctly while the Moto Options 6-4 are messed up.
I was really worried about needing a dish tweak after changing the stacked LNB and I may still, but in my expert opinion, the channel map is messed up.
It certainly isn't the first time.
I sure hope they don't have to emergency spin the code to fix a fatal Moto flaw in the code or roll back the migration schedule.
