Does anyone have a training manual that explains the theory behind Zenith's 
PIP sysytem used in the Model SL3585BT TV. 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.
