I should have mentioned that this set did have a main picture with everything set the way it is now. It just dissappeared leaving only the PIP picture available.

I have one that has a pip but no main picture. The IF, PIP modules have been replaced. Also IC U2900, all the caps in the SMPS have been changed. I am trying to repair this at no cost to a school. Any help would be appreciated. I can download just about anything you care to send me and anyway you want to send it. Any help will get you the thanks of a nice bunch of school kids.
