Chuck, Check to see if you have horz. drive at the base of horz. output if so check for bad vertical output ic p/n 932 212147 687. Pin 5 to ground should be about 8 ohms. Pin 6 should have a vertical drive out if not bad. Also replace d6404 a regular diode to a 75volt zener diode p/n 933 1180000 133. Also check the setting of the G-2 on the flyback this is a critical adjustment.
