It is a question, because I have both jacks: one is labeled Headphone a other one is labeled Service.timreynaert wrote:There is a 3,5 mm Stereo phone jack at back but it is for a headphone. Maybe it is also used as Service Port? There is a serial port because I can change the mode in the service menu.erdem_ua wrote:It's 3,5 mm Stereo phone jack at back of the TV with "SERVICE PORT" label.
You can connect to TV within this port via using serial RS232 connection.
Here is the wiki page for creating a connection.

Re: New C series plays video at correct aspect ratio
I guess, samsung removed service port from back panel. But You could try if that jack is working as RS232...
There is another header soldered on mainboard (at least in our models), so that configuration might set that port.
Reaching to that port requires disassemble your new TV which I don't wanted from you, but anyway you can make it for curiosity
If you make such a thing, please take high resolution pictures for us
Thanks

Re: New C series plays video at correct aspect ratio
It seems to me that Samsung is closing back-doors both in HW and SW, not only for customers, but even for servicemen, but they probably do repairs only as exchange of parts, they don't analyze device thoroughly before repair anymore.timreynaert wrote:It doesn't work via the headphone jack or the pc/dvi audio-in jack.
We would probably have to open the tv...
