Wish you all a happy new year! 
Many Samsung plasma have a feature on the logic board to generate colour bars or other kind of testmode.
This is normally done by shorting a jumper.
Is there a way to activate a testmode on the T-con aswell?
Or perhaps activate from the service menu?
It's so convenient to split the signal chain in two and determine if a failure is caused by mainboard or T-con/panel.
