OK. I understand what happens with plugs disconnected.
With everything in place, tell me what diagnostic LEDs inside the set's 
chassis board are lit, or dark. One LED blinks I understand.The front one?
 Each PS source has a LED to basically tell which circuit  is loading 
whick power supply source. Maybe some sources to your STKs were affected .
