I have a Sony DCR-TRV730 (Digital 8) and the wacking worked for me. I have had this camcorder for about four years and it has worked like a charm until the dreaded C:31:23 message appeared when I tried to record my 3rd grader's school musical performance. I happened to have a CVS reusable camcorder in my camera bag, so I salvaged something of the situation. I went to the Sony site and followed their procedure which did nothing. Thanks to everyone who has shared their experiances. I have my 3rd grader's field day to tape on Friday and now I have my camcorder back in orperation!

I found a message here http://www.globalmediapro.com/av/messages/135625.html where they talk about the error code in terms of bad connection on the PCB. Repairing the camera by smacking it might be explained by getting a better connecting due to the G-Force. However, reading all the negative messages on the internet about Sony products explains me why the company is not doing well. They have a serious quality problem and people start to choose alternatives.

It works! I got a C:31:22 error message on my 4 year old Sony DV camera about 10 minutes ago. I could not believe my luck! I can buy a new camera! YESSS! I thought I'd look online for a solution and found your suggestion. It seemed so... ludicrous... laughable even. I told my wife and she said: "Well, giving electronic equipment a sharp tap is the first thing that engineers do when they're fixing something - just in case it has a loose connection..." What the he11 thinks I... If I hit it hard enough I may still get a new camera! One power off and a sharp tap later... D@mn! It works OK now! I am cursing you for fixing my camera - Now I don't have a good excuse to buy a new one! ;-) Oh, and by the way, my wife also thanks you for saving us a few bucks! Seriously though - Thanks a million - I should get a few beers recounting this story.

RIGHT ON!!! i'll always remember this site for this kind of great advice. My PC-9 has recorded probably about 900 skydives and been used to record archives of another 250 rock shows. i was just trying to capture some video and lo and behold, C:31:22 came up. i have another PC-9, but it's really my wife's camera, and i like to leave the older one plugged in to my studio setup. i held it up about 18" off the ground and dropped it - twice. Second time, it worked just fine!! Thanks! ajpen

we smacked it hit it let our kids have a smack or two nothing please help us we had this camra since our wedding!! please help us

Well yes this does work, never dreamed it. No I didn't bang it against the table but wacked on my leg say 3 times and voila.

I'll be damned. Rely on all my cameras for work, (5 Sony DV's) and was about to replace my PC-9, (best camera I've ever owned and irrepalceable) when I found this post. Smacked it around and called it Sally, lo and behold it works. To repeat another post....does anyone have any experience with how long this "fix" works?
