wow, my wife thought this was a joke , but yup, take the battery out 2 firm hits on both sides and shes good as new, just guttered i just brought a new one last month as i thought it was a goner.

wow... all i can say is wow. i can't believe this worked. thanks. i really have no words to say... exept 'i have no words to say'. again thanks.

lolzzzzzzzzzzzzzz it did not work the tape had d problem but no cool advice man.even still its a bit looloo.lolzz

Wow, I can't believe that actually worked.

i must admit,this is the craziest thing to do but what can i say,it realy does work!!!

Removed the battery for several minutes and performed the slap procedure. Worked like a charm.

C:31:22 is for T reel fault, C:31:23 is for S reel fault, according to the manual..There must be a poor connection with the plug in the reel sensor board..

I had the same problem yesterday w/ my dcr-trv22, a handy gear I use exclusively for capturing my video projects. I've been using it for almost 4yrs and it works well. Then this error message came. I thought it's because of dirty head, so I put the head cleaning tape, but the camera won't play and gave the same message! Thank God and cheers to this thread. I slapped the camera, dropped it twice unto my SOFT CUSHION bed from a height of 10-INCHES. Crazy, but it worked! May have worked for me, but you do it at your own risk though. I have several video cams, so I can spare breaking this one.

on you tube you will find the method to fix your camera just enter the error message and you will find your answer it works 100 %

Thanks a lot. It worked !! I'm from Germany and really happy about this PS: I wrote my story as a new message instead as a reply (mistake,I know). If you want to read it, it's under the subjekt: sony cam c:31:22
