Hitachi 27CX4B Chassis A3LXU1 Chassis MFD Sept 1994 Set MFD Jan 1995 Intmt Shutdown at turn on-HV comes up then shuts down all in about 1 sec or less there is a pronounced Hum in the power supply when shutdown. Have changed regulator no effect. Can get to start with hair dryer but will not reverse back to failure with freeze mist. D744 tested after set started working tests as intact. Ideas? was thinking a connection or cap problem but once starts working no good method to get to stop working one of the types you think you've got it and put it together try quite a bit later and then doesn't come on....
