I have a new model B raspberry pi running Raspbian “wheezy”. It works just fine with HDMI. When I attempted to use the analog video output with an old konka tv, the LEDs displayed normally but no image was displayed. I was able to connect to it through ssh and control it through the cli, so I believe it is booting perfectly fine.
I was able to connect the video output for an old play station 2 and that displayed, so I don't believe there is anything wrong with the tv. I also tried av input with the tv that it works with for HDMI and it said there was no signal. The cable was working with a dvd player before so I don't think it's a cable issue. One thing I did notice was that the old tv seemed to produce a lot of static charge when I first turned it on, so perhaps the analog output on the pi was fried but everything else was left working?
Is there anything I should do to troubleshoot this and/or verify whether or not the analog video is working?
