There were numbers and if you pressed them the display would show checkerboard on 1 & 2, from 3 to 7 the display just keeps getting darker. I don't even know how to set or exit it after getting into that secret menu.
The idea was just to see if the pixels work without fading in the service mode.
Buttons 1 and 2 just change the checkerboard, and in my case all pixels work without fading in the service mode. I was expecting to see the fading problem also with the checkerboard...
You can exit from the service mode by switching off the radio.
