FAILURE: will not start
DESCRIPTION OF FAILURE: when I try to start TV LED lights green, but the TV does not work, SMPS is correct, the collector has BU808DF 111V and also to pin 1,2 and 7 of HV transformer, but the other pins of HV transformer has no voltage (0V ) I replaced the transformer and put the PF-0501-19238 (30017788) again there is no voltage on other pins (only at 1.2 and 7, 111Volti) whether the transformer is not compatible or something else is a defect
