Samsung LCD A330 AV Calibration gone wrong

Well, I have no one to blame but myself... I did the Mute,1,8,2,Power to get service mode open, hoping to find a way to fix a sound issue I was having. I was clicking through everything, and came across AV Calibration. I didn't realize the right arrow would select it, and pressed it. Bad move. Now I can't receive anything through coax, which is an issue considering I have cable. I've tried running a 8x8 checkerboard and a NTSC test pattern while it calibrates, but to no avail. I'm assuming that if nothing happens after 15 minutes, that's a sign that nothing will happen, right? I fear I may have to fess up to Samsung and pay for a repair, but if you have any suggestions, they are most certainly welcomed. The setup I'm using to get the pattern(s) on the screen is a Wii displaying the images, routed through a VCR to get it to come out through coax. I've verified that the image is in fact being outputted correctly by attaching another TV to set it up.

Please guys, I'd rather not have to go to samsung on this one. If anyone can tell me where I could find a service manual for this TV, that would be helpful as well.

In fact, I have not fixed it. Your suggestion would be greatly appreciated.

Thank you so much! I now have a fully functional A330, but I'm not exactly sure what I'm going to do with it, seeing as I already obtained a replacement. This is worsened by the fact that I probably can't return the new Sony. *facepalm* Thanks for reviving my Sammy though!
