Television and Home Theater

First of all I wish to express my gratitude for having this forum available.....

LSS: Our DishNet installer changed the channels on our ancient SONY KV 1929 R set.  It now is programmed to receive ONLY channels 3 & 60.  With anyone's help we would like to bring back more channels. Attaced below are: (1) a YouTube view of the front of our TV set controls and (2) a link to a still photo of the Add/Erase buttons and controls....

 Hi all, does anyone happen to know where I can find a controller panel (p/n X-4032-545-1)? All the searches I've done show it as no longer available. I don't mind getting a used one from an otherwise dead tv, but I don't know where to begin looking. I just got this for free, and one of the reasons is a (rather) large hole in the panel. If I can't find one, I'll be doing some patchwork.

 I believe the other issue has to do with the convergence IC's, but I've already gotten the SM, and will look in to that once I get it home, etc.

Hello everyone!!
