    Very strange flash sequence. Four flashes indicate Vertical problems and seven flashes indicate H.Stop. Whatever the case replacing the D Board will usually solve your problems BUT I've come across poor solder joints on the Deflection Yoke Circuit Board that will cause the same symptoms, and replacing the D Board will not help. The Deflection Yoke is mounted on the CRT neck and plugs into the D Circuit Board at CN502. Usually the wires are colored Red/Blue/Yellow/Green. Eric
