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....
