Where can I get a main board for a Panasonic CT2766E?

The board has a crack in the foil somewhere near the front right (as you look at it from the back). I've soldered everything I can. Picture goes out, tap on board or press on it in that area and picture comes back. Can't see any crack. I'm trying to do a free repair for a local Day Care Center who can't afford to have it replaced or repaired in a shop. Any assistance would be appreciated. You can contact me at hwpete616@yahoo.com.

Thanks
