If you do not have a VGA port on your monitor/display/TV, you will need to use the supplied 3.5mm AV to RCA cable. The AV to RCA cable fits into the 3.5mm jack/port found on the Raspberry Pi. This looks very similar to a regular headphone jack/port. The RCA cable which has the red, white and yellow connectors are to be inserted into the matching coloured ports found on your monitor/display/TV.


Please note, the Raspberry Pi should automatically switch the output method. However, if you are using the 3.5mm AV to RCA cable you'll need to edit the config.txt file to force video output via RCA.


To open your config.txt file, please insert the SD card into another computer/laptop. To find the contents of your SD card navigate to ‘My Computer/This PC’ and select the SD card drive. Here you would be able to open the config.txt file.


There are two lines you need to edit. First, you need to REMOVE the hash symbol (#) from the start of the following line:


# sdtv_mode=2


It should look like this:


sdtv_mode=2


Next, you need to ADD a hash symbol (#) to the start of the following line:


hdmi_force_hotplug=1


It should look like this:


# hdmi_force_hotplug=1


After this has been completed, re-boot your Raspberry Pi.
