Sorry for the overlong post, but we have had 3 weeks of nightmares with our 622 and are hoping that the more information provided the better in finding a solution to our problem.
Here's the story. Upgraded to a 622 3 weeks ago. Within 2 hours of installer leaving the house, screen went blank and "check switch" box came up. Scrolling through the menu to "check the switch" showed a receiver error. (Both TVs controlled by 622 box went out. Separate TVs in other parts of house run from HD-211 and non-HD receivers continued to work fine.)
Installer returned and said that cables from old system needed to be upgraded and proceeded to replace cable to 622.
Within 2 days, same "check switch" failure came up on the new 211 single HD receiver. Tech came out and replaced cable to that receiver.
A few days later, a repeat of the "check switch" and problems acquiring a signal came up on the 622 receiver. After running diagnostics, we eventually recouped some channels in one room and other channels in the other room run off the 622. Overnight the second TV that was not working at all came back with channels. Tech came out and replaced the splitters and the ports.
All was well for about a week and then the "check switch" came up again. All of the same failures came up as diagnostics were run. As before, on the check switch - it would go to 1/38 instead of 1/4 for the check. Tech came out again and this time replaced the 622 receiver and the switch. So now every piece of equipment has been replaced since the initial install. When he left 3 days ago, the tech said he is out of possible solutions and wouldn't know what to do if the problem recurred.
Notably, after the cable to the 211 HD receiver was replaced, we have had no other failures on that set or on the non-HD receiver. So we know that there is nothing wrong with the satellites. Weather is a non-issue.
We are 3 days post the last visit from the tech and the "check switch" came on again. After about 6 reboots, all is working again tonight.
It is possible that each of the "check switch" errors followed heavy remote control scrolling through the channels using either the up/down channel buttons, the use of the scroll on the bottom of the screen done quickly, or entering a particular channel.
We are trying to figure out what is wrong, if we can get around this issue or if it is time to go back to cable!
