Raspberry Pi 2 A/V output via RCA Question.

Question

I have the RP2 running RetroPie and have used it via HDMI.

I now want to use my 3.5mm to RCA cable. I have tried but get not picture. My TV seems to see something is there but I get no audio or video. I have made sure the yellow is in yellow, red to red, white to white and that the 3.5mm is firmly in the RP2.

The 3.5 mm jack has 3 black bands if that helps.

Any ideas?

Thanks.

hello I m new user like you guys to lovely "Raspberry pi 2" ,

i m like you faced the problem in getting output on tv using RCA VIDEO cable,but after some research found a complete solution,

Solution to RCA VIDEO output prolem: Two steps

Step 1:Hardware setup,i,e whatever the rca cable you have bought mostly have the yellow pin with connections in reverse as per Rapberry pi requirement ,

so you the cut yellow wire at distance of 10 cm from male pin and reverse the connection with black to yellow and yellow to black, now you are fit with RCA hardware compatability.

Step 2: If you connect Raspy to tv powered on and then power on your raspy,if you dont see anything on tv (with AV screen on ,for which the Raspy has been connected)

go for "config.txt" editing ,Add the folliwing lines of code, (note:if a line of code already exist dont repeat it)

sdtv_mode=2

hdmi_ignore_hotplug=1

#hdmi_force_hotplug=1

#note above lines added to have composite display,and hdmi will not come,if you want hdmi display on,comment above two lines,and uncomment third line.

i think i have given a quick solution for the problem of not having output on CRT TV using RCA Video cable .

If your problem is solved please comment out,or for any queries.

The cables are not all alike even though they have 4 rings on tip: Check yours in diagram above to correct above.

FYI, (this might help you understand the problem, helping to fix it yourself). So the pi effectively has two "output devices" for each of "video" and "audio". You more or less have to TELL it what output device to use. There will not be any video on the RCA out if you don't tell the 'pi to do RCA instead of HDMI. Similarly the AUDIO can go to HDMI while you want analog out. The audio is capable of switching dynamically. But the video more or less needs to be configured during boot.
