I’ve just bought BBB, I tried Angstrom Linux 05.20, 06.06, 06.17, 06.20 , Ubuntu 12.10, 13.04. There is no HDMI signal. I had checked EDID information and there was an error: “IO error reading EDID”
I use TCL and Samsung TV
What should i do now
Sounds like it cannot read your EDID. You need to make sure all power supplies are plugged into the same power strip and that you display is not in a sleep mode. I also suggest that you try the latest image as well.
