its really works !!! its amazing ..

Its some sort of Mechanical problem, as told by The Sony service centre; wind could cost court 75$.

Thankyou so so much, I had just had my camera rebuilt after it had a trip down the stairs, after getting it back it came up with this error and I had no money to get it fixed again. Found this site, gave it two short sharp tapes and hey presto! If in doubt, give it a clout!

Oh jesus this is hilarious. I have been taping blogs and it flashes C:31:23 ALL THE TIME. normally I take out the tape and leave it, but I tried that a few times and it didn't work. I found this forum and didn't believe it, I was very scared of breaking my camera. So, I turn it off, unplug everything, and start whacking the living S@1* out of it. I b###h slapped the area around where the tape is put in, cringe as I turn it back on, and the error is gone! Thank you!!! haha.

thank your the man...it work to me

Slapping around 10 times anf few hard shakes also worked for me. fixed problem: beeps with sony trv318 c:31:23

help me I slap my camera for my trv 19 but did not work... how to fix it...

Smacking the camera didnt work. I smaked it until my hand hurt. Then I tryed to take the battery of for 60 secs. It didnt work either. Then I read somewhere that you could take a hairdryer and blow in to your camera. And the error just disapeard.

I have been getting the 31:23 and 31:22 errors on 8 out of ten tapes I try to insert. I have a Sony HVR Z1U. The camera is only a year old.... What to do? I heard that it may be a mechanical issue with a small piece possibly having broke loose, or a moisture issue, we are in autumn and the studio is sub-level (basement) - I am not sure what to do. Should I turn on the de humidifier and leave the camera open overnight to 'air out'??? I have been to Egypt and back with this camera- and no probs till now What to do???!!! Help please!

Like most of the others i've had sucess with this fix. My Sony GV-D200E Digital 8 walkman has sat on a shelf for years because i couldn't figure out how to fix the error code. had it apart several times and still no luck until i found this fix, slaped it several times with my hand and now it works like new. Fantastic!!!!!
