Thanks Steven,thought this may be the problem as caught it getting back onto the catamaran.Will try and find my local Pentax repairer.

Hi,
Don't know if anyone has any suggestions,but I have just returned from a lovely holiday,whilst on a snorkelling trip I developed a problem with my Pentax optio w30.It was fine at the begining of the trip but then took 2 pictures at random then I got a series of lines on my screen then just went dead.
I wondered if water had somehow got into the unit so left it a couple of days to dry outbut still nothing.
Upon returning home I fully charged the bettery again and then did get the cemera to switch on but then no matter what button I press the camera just takes picyures automatically and I can not now get out of this mode.
Has anyone got any suggestions or has this happened to anyone else.
I would really appreciate any help from anyone as to what may have caused this.
Thanks in anticipation.
