When I got home this evening, I checked channel 521 (TNT-HD) and it was gone from my fav list. However, it was in the all HD channel list. I tuned to it and the stb rebooted. After reboot, the voom menu appear but there was no signal in the background like it usually does (channel 100). Worried I waited until the message "downloading PG...." went away. After it finished, it gave me all the channels listing without PG but no signal, no picture. I turned off stb and turned it back on using my remote. The signal and picture came back. I left it alone to download the PG.
