Re: L65X1Q_DHS / BN44-00627A Samsung UN65F6400AF Standby blinks twice five times

@Davi.p thanks for your hint.

I never had a bad transformer on a PSU. Got this BN44-00627A here since March and could not fix it. First i found the D2011K damaged. The IC is next to the transformer. Also one UF4007G diode was damaged. I replaced it with a UF4007 only to find out weeks later it's causing trouble. The boost circuit was not working. It needs 390V but was only at around 316-320V. I replaced the UF4007 with the (hard to find) UF4007G which is much quicker and the boost voltage...
