Do I Need The Cali. Mic To Make The System Work
I was given a str-k790 without a calibration mic. Is this going to be a problem in making this system work. I have everything hooked up but nothing is working. I don't know for sure what I am doing but I can follow instructions, I have good common sense and the clock on my dvd is'nt blinking because I do know how to set it.

No, you should not need the mic to make the system work. You can find product documentation/troubleshooting tips, etc, on its product page here:
http://esupport.sony.com/US/p/model-home.pl?mdl=STRK790&LOC=3#/howtoTab
If you're still experiencing issues, I would call Sony:
