А какие конкретно логи надо смотреть?
syslog и все остальные на момент изъятия кабеля. ссылку выше посмотрите, там описана процедура и возможная причина:
It seems like it’s almost an electrical issue, unplugging the hdmi lead is causing something to spike on the board which is causing a crash. That’s how it seems to me anyway. I’d like to find out if the issue is either with the TV, the Pi or the HDMI Lead. So can you try these tests?

The quality of HDMI cables can vary a lot and it might be that the one you have doesn’t have the wires inside insulated very well. That’s just a conjecture though, but if you do the tests above you’ll probably be a bit closer to understanding what is going on.
