Obvirosly i did NOT burn the regulator - sadly... 'cause the problem still persits.
so: step by step, let me explain...
i soldered the new RECOM R-78C12-1.0 into place. Looks good,
now, this didn't change much. After plugging in the 19V transformator: The LED's are still lid, the fans are blowing, the UltiController has it's light blue backlight. But the Ulticontroller is not reacting.
Than i pluged in a USB Connection to CURA 14.09.
Funny enought, that the brighness of the display was altered a little bit. Will say, I saw a very short flickering. And from time to time i could see the faint letters in the display saying things like "Ultimaker Ready" in the last row. But the rest of the display was sooo bright, that there was nearly no contrast between the letters and the background. Therefore it was almost impossible to read, and only stayed on the display for a very short time.
I tried to capture the event in the following foto: (zoom in to see the letters in the UltiController display)
The laptop could NOT connect via USB. There was no way, that i could establish a connection to the printer.
Anyone hase a clue, what could be broken? // Should be fixed??
Any sound advice would be highly appreciated!
Thanks, guys!
