Thnx Beobuddy for responding!
This is what I measured for AC voltage (see also picture).

Left side:

  • 1 + 2 = 0v
  • 2 + 3 = 0v
  • 1 + 3 = 0v

Right side:

  • 4 + 5 = 0v
  • 5 + 6 = 0v
  • 4 + 6 = 0v

Just to be complete, I also measured (again) if 230v AC is coming in at the 230v connector on this PCB. The result: positive, 230v has been measured.

Let me know if this is what you meant?
I assume the T2 transformer is dead. I am just wondering why the behavior of the T2 changed from:

  • Dead (no red LED at all), to
  • Alive with errors (LED changing from red to green and back all the time), to
  • Now dead again.

Interested in your comments and advise.
