^^^
This second CX25843 chip has gone braindead or the I2C bus from the
second CX23416 chip isn't working. That's chip decodes analog video
signals into digital data. Until it responds no video will work.
Check
$ modinfo ivtv
$ modinfo cx25840
and see what debugging options you can turn on in /etc/modprobe.conf for
these modules. It might give insight into what the problem is.
Highest probability cause is that that CX25843 is dead.
If you're lucky, it's only some Linux I2C subsystem problem in software.

Andy
