For the last two days, my 622 is stuck on the "Acquiring Satellite Signal" screen in some sort of loop. It runs through each of the transponders but never gets past "0 of 5" on the tests. I had to unplug and then wait 30 seconds and plug it back in for it to work yesterday (5/2/09). This morning (5/3/09) it started again. I called TS after trying a soft reboot where it still wouldn't work. They had me do another soft reboot and it finally came back. She said she would issue a trouble report. Has anyone else had problems after the nightly update and reboot and what did you do to solve it?
