I lose composite video once I select an OS

[themanchurian]

Hi all,

I have an issue, I turn on my Rpi 2 and press shift, then "4" so I see noob's menu on my TV.
But once I select the OS, whichever I select (got Raspbian and OMSC Kodi) I lose video signal.

Any solutions?

Thank you

Display Mode Selection: By default, NOOBS will output over HDMI at your display's preferred resolution, even if no HDMI display is connected. If you do not see any output on your HDMI display or are using the composite output, press 1, 2, 3 or 4 on your keyboard to select HDMI preferred mode, HDMI safe mode, composite PAL mode or composite NTSC mode respectively.

Note that all user settings (language, keyboard layout, display mode) will persist between reboots and will also be automatically passed to the installed OSes. This means that if you can see the NOOBS interface on your display device then you should be able to see the OS CLI/GUI when it boots too!

In my (limited) experience that works as described at the time you initially install the OS, if you answer Yes to the dialogue box asking if you want to keep the changed output settings.

But it doesn't track changes to the output device after the OS[es] have been installed.

You can do that manually by using the Configuration File editor builtin to the NOOBS Recovery console.

The option you need to change is sdtv_mode. These are the valid options:

Code: Select all

sdtv_mode=0    Normal NTSC
sdtv_mode=1    Japanese version of NTSC – no pedestal
sdtv_mode=2    Normal PAL
sdtv_mode=3    Brazilian version of PAL – 525/60 rather than 625/50, different subcarrier

So it seems that NOOBS setting 4 corresponds with sdtv mode 0.

(Remove the '#' from the start of the line as well.)

Editted to add: look through the whole of the configuration before making changes - NOOBS appends its settings to the end of the file.
