First as I was not here I do not know why the hell he went into the settings... as for the settings being changed by someone else prior... at 7am I watched the local news. at 8am I left my house with everything still intact to go to the office real quick.
Typically I do what others have said and tell the guy to sit on the chair while I hook things up. (and it's what I intend to do tomorrow with the installer that comes out)
In response to the two questions asked of me:
1) I was given the basic settings (Brightness, Contrast, Backlight) which has improved the picture some but I don't have the other settings.
2) I was told by tech support that they "needed" to send someone out. My assumption was that it was better to get a receiver today than to wait until Wednesday (Monday is a federal holiday which means it wouldn't even ship until Tuesday so if they overnighted it I'd get it Wednesday). I had my wife on the phone throughout the install except for five minutes when I called dish because he was trying to put me on the service plan which I was told I would not need and $6 may not be much for one month but if I'm told an additional fee will not apply then it is not going to apply. I had that resolved and called back and he was packing up to go so within that five minute window of me calling customer service is when it happened.
Also, in response to the comment that I may have messed it up... I do not go into my tv settings at all... there is no need as everything runs from my touch screen or the universal remote (so no reason for him to even program a remote since there were two other ways to control the devices without use of a dish remote). I do installs at my work (I am the co-dish installer at my company as well as the on-site av specialist/co-meeting planner) but my eye for color is not good enough to be doing calibrations. My 722 sounded like a jet engine taking off and had a green flashing light on it. The receiver would not even reset and if I unplugged it and plugged it back in the fan/hard drive spun just as fast as before. I watched OTA and Blu-Ray fine all day Friday and yesterday with no color problems.
At any rate the 211s and 722 are waiting off to the side for their respective boxes to go back to their homes.
