the little verticle board has three pins seperate from the other 5 pins. These three pins are close to the secondary side which is the monitor for shutdown. Scoped all three pins for spikes and DC on turnon..nothing...removed small verticale board..removed conductive dried glue..reinstalled ..everything works...conductive aged glue strikes again
