I post because there is nothing on my console. But the wires are conected. My Problem is that I can not enable RS232 like it is described for C/D series:

[MENU] [MUTE] [POWER] --> Enter the Control menu and set the value of the RS232 mode to Debug.
The service menu is like it is described for the E series:

[MENU] [MUTE] [POWER] --> Control -> Sub Option -> RS-232 Jack -> to DEBUG
And I think the jack is an indicator for 3.5 and not VGA. But I'm not quite sure.
