Thanks to all. Ready to trash my DCR-TVR33, but found the 800-222-1669
number. While holding, I found online support at: http://esupport.sony.com/perl/news-item.pl?news_id=161&mdl=DCRTRV33
(I guess several trips to Hawaii and Fuji didn't help the humidity/temperature issues!)
friendly Sony representative had me reset the camera and then offered
to have the problem fixed for free, including shipping.
