It started with giving little bit yellow looking picture, and sometimes it flickered blue. For two weeks problem could be solved just turning tv off and on again, but now it wont give the blue color at all...(so the picture looks like yellow, little greenish).
Cold soldier joint on deflection board (at end of tube). Power unit down and disconnect power. Wait 15 minutes for total discharge and carefully unplug the connections to the board. Resoldier all the CRT connector contacts and sub cables to board. Reconnect all and test. Some low voltage conditions from the HV supply can blank a tube and restarting set can cause the capacitors to charge enough to make it work for a short period of time. This type of failure is most often the flyback degrading and not a regulator.
HI,the usual faults & simple ones are on the CRT bd on the PIX tube neck,by your description id say the blu or red drvs need attention.or supply rail. regards CHOOK.
