I have two Pis: a Rev 1 and a Rev 2. Both 256mb versions.
The Rev 2 board does not output on it's composite video port (or at least nothing displays when plugging a screen in).
The Rev 1 board, with the same cable and same screen, does work.
Obviously, I'd want both boards working, so I did a little investigation. I measured the voltage across the composite port using the solder points for the port on the underside of the Pi.
The Rev 1 measured about 2.5v
The Rev 2 measured about 0.6v
Is this indicative of a problem, or is this just a difference between the two Revisions?
If it is a possible problem, what could I do to fix it? Any ideas?
Hope someone can help,
