Schematic says pins 1 & 7 of Molex go directly to the CRT socket. A
Molex connector, by nature, seems to attract cracked solder
connections. Check your resistances all the way from the CRT to the
Molex pins. If you find a cracked solder connection WICK OFF THE OLD
SOLDER and resolder the pin, don't just reflow the old solder.
