Working on this set, no schematic, it appears that start up is not comming up. I have power to Horiz. output transistor but no startup voltage on horiz. drive transformer. The only thing I find wrong in the horiz. drive circuit is that have no measurment for zener diode (D744). Anyone have tips for this chassis and the value for this diode, TIA Neil TV Doctors Monroe,Wa. ***************************************************************************** CHECK OUT THE NEW CHATROOM!
